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.

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