Looking for the name of an older english time travel movie. A boy and his mother move into a boarding house (?) and at midnight he goes through a door into a garden and is transported to another time.

Tom's Midnight Garden (http://en.wikipedia.org/wiki/Tom%27s_Midnight_Garden_%28film%29)?

That is it. Thanks so much. Thought it had MIdnight in the title, but couldn't remember any more.
