On paper, The Room is a soapy drama about a well-to-do guy – Johnny, played by Wiseau – whose life is ruined by his two-timing wife, Lisa. In practice, the film looks like something beamed in from another dimension: nobody in their right minds would have cast Wiseau – tall, pale, with lank black hair like a fading stadium rocker’s – as a wealthy San Francisco banker. No other filmmaker would write lines like the infamous “I did not hit her! I did not! Oh, hi Mark”, much less film them on such a visibly shoddy set. But this is reality, filtered through Wiseau’s perspective – and for better or for worse (really, mostly for worse) his take on modern American life is unlike any other filmmaker’s, living or dead. In the movie, Dave Franco plays Greg, a handsome occasional model whose ambition and nice-guy earnestness makes up for his tentative early attempts at acting. When Greg first sees Tommy during an acting class, yelling and tearing up the stage, he’s visibly startled. Unlike Greg, Tommy isn’t self-conscious in the slightest. And what’s that strange accent? French? Polish? Fascinated by Tommy’s off-kilter charisma, Greg makes a beeline for him, and the two become friends – united in their desire to become Hollywood stars. Unfortunately, Tommy’s lack of self-awareness is as much a curse as a blessing: he’s fearless while performing (even if it’s in a crowded diner), but also clueless when it comes to engaging with powerful Hollywood producers (Judd Apatow plays one such producer in a toe-curling restaurant scene). Still, Wiseau has something else in his favour: a seemingly bottomless reservoir of cash. So when Greg and Tommy find themselves unable to find acting work – after months of sharing a flat and going to casting calls – Tommy decides to make a movie of his own. It’s debatable, however, whether The Disaster Artist ever succeeds at much more than an amusing re-enactment of a bizarre moment in cinema history. Franco is entertaining as Wiseau, but only in the same way that, say, a Saturday Night Live comedian is at impersonating a Hollywood star or head of state. The lank hair and awkward mannerisms are present and correct, but Franco’s Wiseau feels like a caricature rather than a real human being; the film itself does little to give the sense that Wiseau has much of a past beyond his time in California – an old photo of a young Tommy in front of the Eiffel Tower is as close as we get. While it’s true that Wiseau’s secretive nature makes him somewhat unknowable, the original book gave us far more insight into what Wiseau was like when he wasn’t making his dreadful money-pit of a movie. The Disaster Artist has a few moments of pathos – an acting coach played by Bob Odenkirk smirking at Wiseau’s ineptitude in front of a crowded theatre, for example – but the movie otherwise fails to dig below the surface of a curious and fascinating character. It’s as a feel-good comedy, meanwhile, that The Disaster Artist ultimately succeeds; there’s something incredibly endearing about Greg and Tommy, two clueless dreamers who, almost in spite of themselves, create a one-off work of art. The original book gives the pair more depth; the film, at least, captures their charm. The Disaster Artist is out in UK cinemas on the 6th December.
