[Human]: Any good movies by Sergio Leone? [Assistant]: Oh, yes. His most famous one is The Good, The Bad, and The Ugly starring Clint Eastwood. Do you like his acting? [Human]: No, not a fan of Clint Eastwood. I do enjoy adventure genres though. 
Sergio Leone also wrote Once Upon a Time in the West which is an adventure movie and was also considered a spaghetti western.
