10 Most Pointless CGI Movie Shots Ever

7. Green Screen Rooftop - The Room

It's fair to say that Tommy Wiseau's The Room is a film rife with questionable creative calls, though nothing quite raises the eyebrows like Wiseau's decision to use extensive - and totally unconvincing - green screen effects to shoot the film's rooftop scenes.

Wiseau had these scenes shot on a set hastily thrown together in a car park, with a green screen erected so he could composite a shot of the Los Angeles skyline in post-production.

But what makes this use of CGI truly pointless is that Wiseau actually had a rooftop available to shoot the scenes on, but for reasons that none of the film's crew members have ever been able to ascertain, he opted for gaudy chroma-key instead.

If James Franco's The Disaster Artist is to be believed, it's probably because Wiseau wanted to make a Real Hollywood Movie, and nothing says Hollywood like needlessly splashing cash on perfunctory CGI.

Given that the film's budget somehow ballooned to an absurd $6 million, it's fair to assume that this sequence ended up accounting for a sizeable chunk of that price tag.
