Joel and Ethan Cohen’s folk drama Inside Llewyn Davis keeps looking better and better. Justin Timberlake, Carey Mulligan, Oscar Isaac, and John Goodman are all set to star in the flick which follows a young musician (Isaac) trying to make it in the 1960s Greenwich Village folk scene. Now Showblitz reports that Tron: Legacy star Garrett Hedlund is in negotiations to join the cast. Every actor cast thus far has at least a little musical background, and Hedlund is no different as he showed off his singing chops in Country Strong.

The actor is set to star in Warner Bros.’ Akira, but production on that film was recently halted as the studio wants more time to develop the script. That push on Akira opened up room in Hedlund’s schedule to fit Inside Llewyn Davis in.
