Josh Gad did not confirm that Rick Moranis is returning for 'Spaceballs 2,' but he did say that the actor would feel "like this was a project worthy of his return" if he does appear in the movie. Moranis was previously reported to be reprising his character Dark Helmet in Spaceballs 2, the sequel to the 1987 spoof.
