Famous for his role as Neville Longbottom in the successful Harry Potter franchise, actor Matthew Lewis is turning heads on the cover of Attitude’s June 2015 issue. The 25 year-old actor shows off his new and improved physique after hitting the gym for his romantic comedy, Me Before You. In the movie, Lewis plays a triathlete and personal trainer. Preparing for the role, he shared, “I spoke to the director [Thea Sharrock] and I said it’d be nice to get into the mindset of someone like that, because he’s not drinking alcohol, he’s just eating salads all the time. And I was very interested to know where you go to in your mind to have that level of commitment. So I sort of gave up alcohol–I say sort of, I have given up alcohol.”
