The one that got away? In a new interview with Teen Vogue pop superstar Katy Perry revealed that she was almost cast in ‘The Help’.”There was a time when I was going to be involved in ‘The Help’ — just a small part, I wasn’t going to be Emma Stone or anything — but I couldn’t because the shooting schedule conflicted with the release of my record,” Perry told the magazine. “I was upset about that; I knew it was going to be an important film. Not that I need to do drama first, but I do want to do something that makes a strong impression.”Perry has already made some impression on the big screen with her voice. The singer voiced Smurfette in last summer’s reboot of ‘The Smurfs’. She also appeared on episodes of ‘How I Met Your Mother’ and ‘Raising Hope’.While it’s not a prestige film like ‘The Help’, Perry does have a feature hitting screens this summer: ‘Part Of Me,’ a 3D concert film-cum-documentary that details her rise to fame. That film will arrive on July 5.
