I didn’t make that connection either – but a long time ago he was Billy in ‘One Flew over the Cuckoo’s Nest’ –
also strange was the twist that in Dune Sean Young’s (Chani) father, Ecologist Keynes ( a relationship not made apparent in the film) is played by Max VonSydhow… interesting then that in the remake of A Kiss before Dying Max starring Sean Young and Von Sydhow he again plays Sean’s father…
