The Godfather (1972)
Can you adlib an animal? Apparently so! Director Francis Ford Coppola ended up finding this cat on a Paramount lot and ended giving it a place on Marlon Brandoâs lap. The cat was so happy in his spot that his purring ended up messing with some of Brandoâs lines post-edit, so they had to be looped. This ended up creating one of the most iconic looks in all of movie history… Including being the inspiration for tons of Halloween costumes!
