Michael Keaton starred as Batman 28 years ago in Tim Burton’s Batman. Now he’s making his way back to the world of superheroes as the villain in July’s Spider-Man: Homecoming. Keaton was a guest on Ellen today and was asked what the difference is between the two movies.

“One’s a bat and the other’s a spider,” Keaton joked. His real answer is that the way the movies are made are much different, though in the clip below his full answer appears to be edited out. Keaton took time to praise director Tim Burton before talking about what it was like working with Marvel on Spider-Man: Homecoming.

Earlier this year, Spider-Man: Homecoming star Tom Holland said that Micheal Keaton would say “I’m Batman” during their fight scenes, and recite other Batman lines as well.
