Getting verbally trashed by Kenny Powers was only the beginning ... because Marilyn Manson tells TMZ he's got more ACTING ROLES on the way in 2014.

Manson was leaving a silent movie theater in L.A. this week when we brought up his awkwardly hilarious cameo on "Eastbound & Down" and asked if there's a chance he'll ever win an Academy Award.

"I'm gonna win an Oscar??? Nah, I don't think so ..."

But Manson seemed genuinely excited for his future gigs in front of the camera -- he's just not revealing what they are ... yet. 

Check out the clip.
