The cinema of English-speaking Canada is heavily intertwined with the cinema of the neighbouring United States: though there is a distinctly Canadian cinematic tradition, there are also Canadian films that have no obvious Canadian identity (examples include "Porky's" and "Meatballs"), Canadian-American co-productions filmed in Canada (including "My Big Fat Greek Wedding" and the "Saw" series); American films filmed in Canada (including the "Night at the Museum" and "Final Destination" films, among hundreds of others); and American films with Canadian directors and/or actors. Canadian directors who are best known for their American-produced films include Norman Jewison, Jason Reitman, Paul Haggis, and James Cameron; Cameron, in particular, wrote and directed the highest and third highest-grossing films of all time, "Avatar" and "Titanic", respectively.
