What film would you double-bill this with?
Like so many of you out there I'm a big fan of Somewhere in Time. Here's a few suggestions that would make a nice second feature to accompany it on a double-bill:
Maytime (1937) - The third of eight films that teamed Jeanette MacDonald with Nelson Eddy, this one is loosely adapted from Sigmund Romberg's 1917 operatta. Not a time-travel story but most of it is presented as a flashback with Jeanette as a famous opera singer. John Barrymore plays her rather brusque martinet/autocrat manager. She agrees to marry him out of gratitude rather than love. Then she meets handsome but penniless Nelson. A truly lavish and large-scale MGM musical with sumptuous sets and costumes. Reputedly this was MacDonald's favorite of all her films.
A Connecticut Yankee in King Arthur's Court (1949) - Mark Twain's story of an American who time travels back to Ye Olden Days of Camelot is transformed into a lush Tecnicolor vehicle for Bing Crosby. This is a bit lighter fare than SIT and Maytime but it's a lot of fun. Der Bingle's leading lady is the incredibly beautiful red-haired Rhonda Fleming. Also on hand or William Bendix, Sir Cedric Hardwicke (as a rascally King Arthur), and Murvyn Vye (as a very slimy Merlin). I love the song "Busy Doing Nothing".
I'll Never Forget You (1951) - Very simular to SIT. Tyrone Power plays an American in England who feels it's his destiny to travel back in time to the 1700s and exchange places with one of his ancestors and marry his cousin. He does indeed make the trip, only to find himself in a dingy world in which he doesn't belong. Plus he didn't count on his betrothed to have a beautiful and winsome young sister (Ann Blyth). A nice touch: The modern scenes are in black and white while the period scenes are in Technicolor.
These are my choices. What are yours?
