Alien 3 (for Gothic horror and a dreadful ending).
Alien (For production design,the combining of terror with sexuality).
Alien resurrection ( For Fun with the french)
Aliens ( I admire James Cameron, Avatar, Titanic, But even my favorite of his films The Terminator is a rip of of Harlan Ellison and the Grandfather paradox. ALIENS is a ripoff of Robert A. Heinlein's novel, Starship Troopers.
