One of the weirdest things to me about The Room is that there's a specific actually good inspiration in another movie that Wiseau is basing his performance off of and once you know what it is you can ABSOLUTELY hear it

The Room - "Oh Hi Mark" (Blu Ray) [1080p]

he's still doing terrible and not touching anything resembling human speech at any point but like

Rebel Without a Cause (1955) - Stand Up For Me! Scen...

this is what he's GOING for

The Room- You are tearing me apart- Full Scene

better scene for comparison

According to the Disaster Artist (book version) Wiseau had a weird fixation on James Dean.

you could put "You're tearing me apart, Lisa" into Rebel Without a Cause and James Dean would actually make it work

youre tearing me apart lisa!!!
