Rupert appeared on Access Hollywood Live yesterday ahead of next month's official opening of It's Only a Play on Broadway.
Giving credit to the star-studded cast, Rupert says, "I remember looking around during the first table read and thinking to myself 'What am I doing here?!'", briefly mentioning Sir Frank's kleptomaniacal tendencies.
Rupert tells of a growing bond with Stockard Channing, commenting "our characters are quite close in the show", then telling that he and F. Murray Abraham have been out to see a jazz band or two (!).
New images from the show are also included, with Rupert dropping some fun tidbits about signing Ed Sheeran albums, and the trouble he's had removing eyeliner (we feel your pain, Rupert).
