Mr Bannon also made a series of political documentaries, and was an investor in the hit TV sitcom Seinfeld.
A possible return to Hollywood would put him at odds with the views of the vast majority of senior figures in the film industry.
This week he began a war of words with George Clooney who called Mr Bannon "a little wannabe writer who would do anything in the world to have had a script made in Hollywood".
Speaking at the Toronto Film Festival, Clooney called a Bannon script "one of the worst I've ever read".
The script in question was a hip-hop musical set against the backdrop of the 1992 Los Angeles riots and loosely based on Shakespeare's Coriolanus.
Mr Bannon responded: "I don't need to be lectured by a bunch of limousine liberals from the Upper East Side of New York and from the Hamptons."
There have been suggestions, as yet unconfirmed, that Mr Bannon will speak next month at Berkeley, the liberal California college.
At an event there this week police were on hand amid protests as former Breitbart editor Ben Shapiro spoke.
He was invited by campus Republicans, who say the liberal university stifles the voice of conservative speakers.
Berkeley spokesman Dan Mogulof estimated security costs for that event may have been up to $600,000.
