I think I'm going to wind up seeing Best Friends before I see the Disaster Artist.
Seriously, I had so much hope in what Disaster Artist could have been, and when I heard Franco was doing it all I could think of is please don't make the act a parody. Don't base the voice upon the meme that Tommy always says "huuuuuuhhhhhhh?" with such a long draw all the time. Don't be half assed with the vocalizing and expressions.
On the other foot, since Best Friends is actually starring Tommy, who never portrays himself as a parody, I can expect a more authentic performance from him.
