Well, hell. The cast of the upcoming Smurfs feature film is coming together, and it looks like the unflappable Alan Cumming (Gutsy Smurf, really?) may have just hit a speed bump on the highway of coolness. Also, there’s the further probable annoyance of Cumming’s voice sharing a screen with that of Katy Perry, according to Variety:

Jonathan Winters, George Lopez, Katy Perry and Alan Cumming are seeing blue. The foursome is in various stages of talks to lend their voices to Sony’s live-action/animated “Smurfs” movie.

The 84-year-old Winters, who voiced multiple characters on the long-running Hanna-Barbera cartoon version of “Smurfs,” will play Papa Smurf. Pop singer Perry is in talks to portray Smurfette, Alan Cumming is taking on Gutsy Smurf and George Lopez is onboard as Grouchy Smurf.

Neil Patrick Harris has already signed on as the project’s live-action character.

Oh, and about that last bit of cassting news? Essentially, joining this franchise will not only put Neil Patrick Harris back in “Doogie Howser” dorkdom, but he’ll also be lowering himself to the same sort of frantic live-action/animation miming that Jason Lee executed in Alvin and the Chipmunks. Even worse, it’s gonna be in 3-D.
