sorry but can someone help me ... there was this movie maybe made in the 80s about this family that traveles in a car that can go places like the past or underwater. i saw it as a kid and dont remember much of it. i think the movie had 2 parts cause i remember seeing it more than once.

i'd appreciate the help, also if someone else is looking for a movie you can post here.

Edit:  Mike found it for me its "mom and dad save the world" XD
