Berkeley Square (1933)

After inheriting a stately home in London, a modern American man becomes convinced that he can interact with the former inhabitants in their time, 149 years prior.  If he's right, he just has to be sure not to mess anything up while there.

It’s a cool premise that should have been used to much better effect than just having the man from the future come off as weird and kinda scary to the old timers.
