You can live in the past if you try hard enough

Have you seen Berkeley Square? In this 1933 film, Leslie Howard wills himself back to the time of the American Revolution, and the life of an ancestor. The poor ancestor, however (also played by Howard) finds himself exchanging places with his 20th-century descendant, with no idea how or why he got there, or what hit him. Rather than the grand romance of Somewhere In Time, it plays as a mostly light and charming, fish-out-of-water comedy of manners.
