Leave it to Conan O’Brien to ask the geekiest question, and to get the funniest answer. Yes, Chris O’Donnell does have his old Robin costume, and he keeps it in a wooden crate in his basement.
The Batman Forever and Batman & Robin actor told Conan that he asked to keep one of the Robin costumes after filming. O’Donnell joked that his wife kept the costume “next to the bed,” but admitted he keeps it in the crate and has been lugging it around with him as he moved for the last 20 years.
