I'm looking for the pair of actors playing as a couple or romantically involved in the most unrelated movies.
For example, Emma Stone and Ryan Gosling were romantically engaged in 3 separate movies: Crazy, Stupid, Love, then Gangster Squad and finally La La Land.
I'm looking for unrelated movies: Julie Walters and Mark Williams (Ms. and M. Weasley in Harry Potter) count for one, even though it was eight movies.
And I'm looking for couple or romance (even though the line might be hard to tell between romance and friendship in some movies). For example, Jennifer Lawrence and Bradley Cooper have a count of three (Silver Lining Playbook, Serena and American Hustle), as they were not romantically engaged in Joy.
