Michael Keaton had an emotional reaction to seeing the original Batcave for the first time in 30 years on set of The Flash.
"When [Keaton] arrived to the set, the Batcave was already finished and it was lit and everything. He stayed like this [eyes wide] for a while. I didn’t want to interrupt him. I just wanted for him to take it in. Who knows what was going on there? But something was going on there," director Andy Muschietti told IGN.
