Floyd Mayweather Jr. — who’s expected to make up to $100 million this year with an upcoming fight against Saul “Canelo” Alvarez that’s expected to break pay-per-view records — wants to fatten his wallet further by getting into Hollywood. “I’m real good friends with [“The Matrix” franchise producer] Joel Silver,” Mayweather tells the new Maxim. “I could be in front of the camera or behind the camera. I think I could act.” But the prospect may not be all that exciting for the boxer, who scribe and Page Six alum Chris Wilson reported dozed off in the middle of the interview. Mayweather said his fave films include “Training Day,” “Troy,” “Gladiator,” and his top pick, “Let’s Do It Again,” starring Bill Cosby, Jimmie Walker and Sidney Poitier.
