Michael Douglas has become known for his dapper appearance in movies; he was one of the original wolves of Wall Street, after all, and he looks very good in a suit. Occasionally, however, he’s ventured into different territory when it comes to his roles–think grizzled, troubled writer Grady Tripp in Wonder Boys–and now he’s about to revisit a look he hasn’t had in over three decades: a goatee.

Douglas said he grew the facial hair for his part in Ant-Man, the much-anticipated Marvel film starring Paul Rudd.

“I play the former Ant-Man. I’m a professor and scientist . . . a mentor to [the young Ant-Man] Paul Rudd,” Douglas told the New York Post.

Douglas has a couple of projects this year–And So It Goes and indie sensation The Reach–and, according to IMDB, has signed on for Unlocked, which doesn’t have a release date yet. The actor has been going strong as he continues to recover from tongue cancer, which was at first believed to be throat cancer.

Douglas spoke recently about his health ordeals at the International Federation of Head and Neck Oncologic Societies 5th World Congress, saying chemo and radiation left him feeling awful while he was battling cancer.

“I went through seven weeks of radiation and chemotherapy, which somehow seemed very accurately mapped to the seven circles of hel. Each week I sank a little lower and I felt a little — no, I felt a lot worse…The doctors and nurses at Sloan Kettering had warned me not to expect to feel great the moment those seven weeks were over — that there would be another five weeks of feeling pretty awful until I could even hope to improve. All of that was enormously important. Like a soldier, I prepared for battle. … It was my job to toughen up and get ready for the treatment and later on for my recovery, and that’s what I was able to do,” he said.

Ant-Man also stars Evangeline Lilly and Judy Greer and is set for release next July.
