Roman Polanski didn’t attend for obvious reasons, given that he was, and still is, a wanted fugitive. Henry Fonda didn’t attend when he won due to poor health, hence why his daughter Jane accepted on his behalf. Katharine Hepburn would never have attended anyway because she only ever made one Oscars appearance (in a year where she wasn’t even nominated), plus, at the time she won for On Golden Pond, she was on Broadway performing in a play called The West Side Waltz.
