VIOLETS ARE BLUE
Violets are Blue is only major motion picture, that I know, to filmed in Ocean City. Runaway Bride (1999) and Tuck Everlasting (2002) (which also featured Sissy Spacek) shot quite a few scenes in Berlin, just outside of Ocean City. The Atlantic Hotel Inn & Restaurant can be seen in both of those movies.
The Maryland Coast Dispatch has a really good article about Violets are Blue, the 1986 movie starring Sissy Spacek and Kevin Kline that was filmed entirely in, and around, Ocean City, MD. Lots of interesting anecdotes.
