Shannon Lee announced on Friday that her company, Bruce Lee Entertainment, would cooperate with two other Hollywood producers, Lawrence Grey and Janet Yang.

No star or director has been named for the film.

Shannon said the film would explore her father's writings, art and philosophy in addition to his martial-arts stardom.

"There have been projects out there involving my father, but they've lacked a complete understanding of his philosophies and artistry," she said. "They haven't captured the essence of his beliefs in martial arts or storytelling. The only way to get audiences to understand the depth and uniqueness of my father is to generate our own material."

Block, whose previous credits include and , will base his film on a magazine article and has lined up a star in Hong Kong actor Donnie Yen Ji-dan, who played Lee's mentor, Ip Man, in a series of biopics. But despite discussions, Block has not reached an agreement with Bruce Lee Entertainment, the company set up by Shannon and Lee's widow, Linda Lee Cadwell.

The rival film projects reflect an international fascination with Lee, who died at the age of 32 in 1973. He has been the subject of a series of films, documentaries and television series - often accompanied by legal disputes within the Lee family and heated rows about the star's legacy.

Caldwell and Shannon own Lee's personal copyright, and the 1993 US biopic was based on a book by Cadwell. But the film was criticised by some fans for skipping over family matters.

In 2010, Bruce's brother Robert Lee, served as executive producer for a Hong Kong biopic, . The film's producers received a flurry of legal letters from Shannon's solicitor before its release.

Wong Yiu-keung, chairman of the Bruce Lee Club of Hong Kong - of which Robert is honorary chairman - said it would be difficult for anyone to play the legend.

"Bruce is not Gandhi or Mandela. He's an actor himself," he said. Copyright issues meant filmmakers had to avoid certain aspects of Bruce's life, he added.
