It’s fairly uncommon for Marvel Studios to sanction a video being filmed on one of their sets, but they will do it for a good cause. Ant-Man and the Wasp star Paul Rudd showed off the San Francisco set and his new suit in a video for Jon Stewart’s Night of Too Many Stars special on HBO to benefit autism education. Rudd was delighted to answer questions from the dedicated fans who’ve followed his entire career.
