He fired Ben Affleck’s character in “The Company Men,’’ starred alongside Eliza Dushku, Joey McIntyre, and Amy Poehler in the local movie “On Broadway,’’ and, more recently, appeared in the Westport film “Frank the Bastard’’ with Chris Sarandon. But Lance Greene’s latest project has nothing to do with the movies; the actor, who was also one of the producers of “On Broadway,’’ is raising money to fight prostate cancer. He was diagnosed with the disease over the summer and went through a radical prostatectomy earlier this month. “So, in honor of my new found friends battling this cancer I have joined an effort to help raise awareness and funds,’’ Greene explained to friends and family in an e-mail. “Moustache Season is upon us, so I’ve registered for Movember to embrace the hair of the wild. I’ve pledged to cultivate a genuine 100% face grown moustache for 30 days to raise awareness and funds for men’s health, specifically cancers affecting men.’’ Greene held a benefit for his “Mo Better Boston’’ team on Saturday at Orleans, where he has tended bar. Guests included his “On Broadway’’ director Dave McLaughlin, and his local pals Adam Hockman, Chris Wilson, and David De Beck. The facial hair campaign known as Movember - which has an online home at Movember.com - aims to raise money and awareness for men’s health issues.
