‘Behind the Camera’ has eye on ‘Mork’

Hollywood loves to portray its wildest stars. Still, a couple of actors were so furious and frenetic that they almost defy portrayal.

Consider John Belushi in the 1989 movie “Wired.” The role went to – of all people – “The Shield’s” Michael Chiklis, then an enthusiastic unknown.

In “Behind the Camera: The Unauthorized Story of ‘Mork & Mindy,’ ” a TV movie airing Monday night at 9 on NBC, Robin Williams is played by Chris Diamantopoulos, another enthusiastic unknown.

The 29-year-old Diamantopoulos’ longest stint had been two “American Dreams” episodes as Coach Tom Berg. Then his agent phoned, told him about the “Mork” movie, and asked if he had a Robin Williams impression.

“I sort of lied,” he says, “and said, ‘Yes! You kidding me? I’ve been doing Robin Williams for years!’ “

Then he had to quickly study old tapes and interviews. He ended up getting the part and a chance to portray a wild ride.

The film takes Williams from performing for tips in San Francisco to sparking a show that finished No. 3 in the Nielsen ratings its first season.

It watches him struggle with censorship, cocaine, network officials and the show’s quick collapse, along with the dizzying effect of fame itself.

So far, NBC has produced a few “Behind the Camera” films, which often take an unflattering look at some of the nation’s most popular TV shows, like 2003’s “Behind the Camera: The Unauthorized Story of ‘Three’s Company,’ ” and last year’s “Behind the Camera: The Unauthorized Story of ‘Charlie’s Angels.’ “

Later this year, viewers can expect a “Behind the Camera” movie on “Diff’rent Strokes” with both Gary Coleman and Todd Bridges serving as consultants.
