Dave Franco and James Franco in “The Disaster Artist.” Contributed

So, if you make a biopic surrounding the making of a god-awful film turned cult hit, could that potentially make the biopic even worse than the original film? I can’t accurately say, because I might have been the only individual at the work-in-progress premiere of James Franco’s “The Disaster Artist” who hadn’t seen its inspiration, “The Room.”

“The Room” is a 2003 independent romantic drama directed, produced, written and starred in by Tommy Wiseau. It’s arguably the best worst film ever made, and people love this movie — not quite “Rocky Horror Picture Show” love, but it might get there one day.

“The Disaster Artist” is based on Greg Sestero’s book “The Disaster Artist: My Life Inside ‘The Room’”; Sestero starred in “The Room” and is played by Dave Franco in “Disaster.” James Franco gives a hilarious performance as Wiseau, the mysterious renaissance man behind “The Room,” and the most intriguing thing about the biopic is Wiseau himself.

The strange thing that is difficult to get past in “The Disaster Artist” is that everything feels like a caricature of a caricature, which gives the film a plastic sheen that is only salvaged by the Franco brothers’ natural chemistry.
