Interesting thing about Bugsy Malone is that when u watch a 12yr old Jodie Foster in it u are immediately taken back by the fact how natural & professional she is as an actor. It was evident from the very beginning that this prodigious girl would end up becoming a legend.
Also don’t forget the great Paul L. Smith as Hamidou, the sadistic prison guard in Midnight Express filmed on the island of Malta in 1978. Punched his Malta ticket again in 1980 to harass Robin Williams Popeye as Brutus!
How about the great Pepe Cerna? Filmed Buckaroo Bonzai in the eighth dimension in L.A. then flew cross country to get killed in a bathtub by a chainsaw in South Beach for Scar Face. Now that’s acting.
