Lee had his first role as a baby who was carried onto the stage.
By the time he was 18, he had appeared in twenty films.
While in the United States from 1959–1964, Lee abandoned thoughts of a film career in favour of pursuing martial arts.
However, a martial arts exhibition on Long Beach in 1964 eventually led to the invitation by William Dozier for an audition for a part in the pilot for Number One Son.
The show never aired, but Lee was invited for the role of Kato alongside Van Williams in the TV series The Green Hornet. The show lasted just one season, from 1966 to 1967.
Lee also played Kato in three crossover episodes of Batman. This was followed by guest appearances in three television series: Ironside (1967), Here Come the Brides (1969), and Blondie (1969).
At the time, two of Lee's martial arts students were Hollywood script writer Stirling Silliphant and actor James Coburn.
In 1969 the three worked on a script for a film called The Silent Flute and went together on a location hunt to India.
The project was not at realised at the time, but the 1978 film Circle of Iron starring David Carradine was based on the same plot.
In 2010, producer Paul Maslansky was reported to plan and receive fundings for a film based on the original script for The Silent Flute.
In 1969, Lee made a brief appearance in the Silliphant penned film Marlowe where he played a henchman hired to intimidate private detective
Philip Marlowe (played by James Garner) by smashing up his office with leaping kicks and flashing punches, only to later accidentally jump off a tall building while trying to kick Marlowe off.
The same year he also choreographed fight scenes for The Wrecking Crew starring Dean Martin, Sharon Tate and featuring Chuck Norris in his first role. In 1970, he was responsible for fight choreography for A Walk in the Spring Rain starring Ingrid Bergman and Anthony Quinn, again written by Silliphant. In 1971, Lee appeared in four episodes of the television series Longstreet written by Silliphant.
Lee played the martial arts instructor of the title character Mike Longstreet (played by James Franciscus), and important aspects of his martial arts philosophy was written into the script.
According to statements made by Lee, and also by Linda Lee Cadwell after Lee's death, in 1971 Lee pitched a television series of his own tentatively titled The Warrior, discussions which were also confirmed by Warner Bros.
According to Cadwell, however, Lee's concept was retooled and renamed Kung Fu, but Warner Bros. gave Lee no credit.
However, Warner Brothers had for some time been developing an identical concept, created by two writers and producers, Ed Spielman and Howard Friedlander.
According to these sources, the reason Lee was not cast was in part because of his ethnicity but more so because he had a thick accent.
The role of the Shaolin monk in the Wild West, was eventually awarded to then non-martial artist David Carradine.
In a 9 December 1971 television interview on The Pierre Berton Show, Lee commented about Warner Brothers' attitudes towards casting in the series : "They think that business wise it is a risk.
I don't blame them.
If the situation were reversed, and an American star were to come to Hong Kong, and I was the man with the money, I would have my own concerns as to whether the acceptance would be there".
Producer Fred Weintraub had adviced Lee to return to Hong Kong and make a feature film which he could showcase to executives in Hollywood.
Not happy with his supporting roles in the United States., Lee returned to Hong Kong.
Unaware that The Green Hornet had been played to success in Hong Kong and was unofficially referred to as "The Kato Show", he was surprised to be recognised on the street as the star of the show.
After negotiating with both Shaw Brothers Studio and Golden Harvest, Lee signed a film contract to star in two films produced by Golden Harvest.
Lee played his first leading role in The Big Boss (1971) which proved to be an enormous box office success across Asia and catapulted him to stardom.
He soon followed up with Fist of Fury (1972) which broke the box office records set previously by The Big Boss.
Having finished his initial two-year contract, Lee negotiated a new deal with Golden Harvest.
Lee later formed his own company Concord Productions Inc. (協和電影公司) with Chow. For his third film, Way of the Dragon (1972), he was given complete control of the film's production as the writer, director, star, and choreographer of the fight scenes. In 1964, at a demonstration in Long Beach, California, Lee had met Karate champion Chuck Norris.
In Way of the Dragon Lee introduced Norris to moviegoers as his opponent in the final death fight at the Colosseum in Rome, today considered one of Lee's most legendary fight scenes and one of the most memorable fight scenes in martial arts film history.
The role was originally offered to American Karate champion Joe Lewis.
In late 1972, Lee began work on his fourth Golden Harvest Film, Game of Death. He began filming some scenes including his fight sequence with 7'2" American Basketball star Kareem Abdul-Jabbar, a former student.
Production was stopped when Warner Brothers offered Lee the opportunity to star in Enter the Dragon, the first film to be produced jointly by Golden Harvest and Warner Bros. Filming commenced in Hong Kong in February 1973.
One month into the filming, another production company promoted Bruce Lee as a leading actor in Fist of Unicorn, although he had merely agreed to choreograph the fight sequences in the film as a favour to his long-time friend Unicorn Chan.
Lee planned to sue the production company, but retained his friendship with Chan.
However, only a few months after the completion of Enter the Dragon, and six days before its 26 July 1973 release,Lee died.
Enter the Dragon would go on to become one of the year's highest grossing films and cement Lee as a martial arts legend. It was made for US$850,000 in 1973 (equivalent to $4 million adjusted for inflation as of 2007).
To date, Enter the Dragon has grossed over $200 million worldwide.
The film sparked a brief fad in martial arts, epitomised in songs such as "Kung Fu Fighting" and TV shows like Kung Fu.
Robert Clouse, the director of Enter the Dragon, and Raymond Chow attempted to finish Lee's incomplete film Game of Death which Lee was also set to write and direct.
Lee had shot over 100 minutes of footage, including out-takes, for Game of Death before shooting was stopped to allow him to work on Enter the Dragon.
In addition to Abdul-Jabbar, George Lazenby, Hapkido master Ji Han-Jae and another of Lee's students, Dan Inosanto were also to appear in the film, which was to culminate in Lee's character, Hai Tien (clad in the now-famous yellow track suit) taking on a series of different challenge on each floor as they make their way through a five-level pagoda.
In a controversial move, Robert Clouse finished the film using a look-alike and archive footage of Lee from his other films with a new storyline and cast, which was released in 1978.
However, the cobbled-together film contained only fifteen minutes of actual footage of Lee (he had printed many unsuccessful takes) while the rest had a Lee look-alike, Kim Tai Chung, and Yuen Biao as stunt double.
The unused footage Lee had filmed was recovered 22 years later and included in the documentary Bruce Lee: A Warrior's Journey.
Apart from Game of Death, other future film projects were planned to feature Lee at the time.
In 1972, after the success of The Big Boss and [[Fist of Fury], a third film was planned by Raymond Chow at Golden Harvest to be directed by Lo Wei, titled Yellow-Faced Tiger. However, at the time, Lee decided to direct and produce his own script for Way of the Dragon instead.
Although Lee had formed a production company with Raymond Chow, a period film was also planned from September–November 1973 with the competing Shaw Brothers Studio, to be directed by either Chor Yuen or Cheng Kang, and written by Yi Kang and Chang Cheh, titled The Seven Sons of the Jade Dragon.
Lee had also worked on several scripts himself. A tape containing a recording of Lee narrating the basic storyline to a film tentatively titled Southern Fist/Northern Leg exists, showing some similarities with the canned script for The Silent Flute (Circle of Iron).
Another script had the title Green Bamboo Warrior, set in San Fransisco, planned to co-star Bolo Yeung and to be produced by Andrew Vajna who later went on to produce First Blood.
Photo shoot costume tests were also organized for some of these plannned film projects.
