The Disaster Artist was born thanks to a book published in 2013, written by Greg Sestero (and Tom Bissell) about how he met Tommy Wiseau, how their very unlikely friendship developed and most importantly a behind the scenes look at possibly the best worst movie ever made. And that is exactly what this film is about.
You might enjoy this movie even if you are wandering who the fuck Tommy Wiseau is, but if that is the case, it would be impossible to get the full experience because let’s be honest, watching The Room before The Disaster Artist is an absolute must.
Sestero said to Rolling Stone the book told the story "as honest as you can get", only omitting certain details to respect Tommy’s wishes.
Franco’s movie also kept some specifics off the record, like the fact that production went through three different crews during filming.
Don’t expect to get out of the screening having all your questions answered, like how old Tommy is, how he came across the endless amount of money he seems to have or even where he’s from, but since Franco’s film is very close to the real events (Wiseau himself said is 99.9% accurate), you will have the knowledge you never dreamt of having on your favorite guilty pleasure movie and most importantly it will leave a big smile on your face.
Cameos were plentiful, but some didn't make the final cut like the scenes with Jim Parsons, Kate Upton, Eliza Coupe, Zach Braff and even Greg Sestero as an assistant casting director - hopefully we'll get all that in the DVD.
The segment with Zac Efron did end up in the movie (even though it wasn’t until much later that I realized who he was... oops!). I really enjoyed seeing Bryan Cranston as himself but bare in mind that whole story arc never happened, which I'm glad because the whole thing didn't put Tommy in a very flattering light.
Of course the "true American hero/ vampire" Tommy showed his face (as he demanded according to contract) making an appearance as a Johnny Depp looking dude in a Marvel like end credit scene. So stay until the very end.
James Franco did a fantastic job impersonating the very peculiar Tommy Wiseau, and I didn’t expect anything less (he even directed the whole thing while in character!), but so was everybody else involved in the making of the fictional The Room.
The whole cast was more than perfect playing their real life counterparts, but you don't have to take my word for it since at the end of the movie there is a frame next to frame showing of a bunch of the scenes - In fact, more than 20 minutes of The Room was created for this film down to every line and mannerism.
Conclusion: you need to see this film, not because James, Dave Franco or Seth Rogen, do it because it is a passion project about a passion project, "real Hollywood emotions" and it is piss funny, Dan almost drowned on his Coke Zero while watching. It is THAT good!
