Amid all the hubbub over Star Wars: The Force Awakens last year, Bill Hader became the droid everyone was looking for when it was revealed he acted as a vocal consultant on the film for BB-8.

“J.J. Abrams called me and said, ‘Hey man, do you want to do a voice in Star Wars,’” Hader told Jimmy Kimmel about the experience on Wednesday’s Jimmy Kimmel Live. “He didn’t tell me it was the new R2-D2 character.”

Hader and actor Ben Schwartz helped bring BB-8 to life with vocal sounds – Hader’s produced using an iPad and a talk box – but the SNL vet said he wasn’t expecting any kind of credit.

“It was a giant surprise,” Hader said of seeing his name in the Star Wars credits, the first time anyone realized he had participated in the film. “I didn’t know about it until I was watching the movie and my name came up.”
