The 26-year-old star was attending the MTVU Woodie Awards in November when Leto, who is the lead singer of cult act 30 Seconds to Mars, approached his table.
Wood tells Jane magazine, "He was basically upset at the fact that I said I didn't like his band. He said that initially and walked away.
"I guess he thought I was laughing at him, but I was more shell-shocked and telling people around me, 'Whoa, I just got told off by Jared Leto for not liking his band.' And that's when he came back and grabbed me."
He adds, "I told Jared it wasn't personal. He acted like I'd been disrespecting him or speaking about his family.
"Things like that don't usually happen to me. I'm very non-confrontational. The whole thing was kind of ridiculous."
