Please tell me this movie is real and I'm not crazy...?

I saw a movie a long time ago, but i don't remember the name, and when I tell people about it,they say they never heard of it.The in my acting class some people said they heard about it,but don't know the name.

In the beginning there is a family of 4,mom,dad,daughter, and son.The father & 2 children are killed(in a car crash i think).The mom is so depressed with life she commits suicide & goes to hell.The father(who is in heaven) found out she killed herself and was stuck in hell & wants to bring her back to heaven with him. In the end he brings her to heaven.to find the children grew up.& then the mom & dad decide to be born again&live their life all over again(of course they wont remember heaven or hell).The kids say they will be with their parents again one day.& at the end of the movie the dad is a little boy on a dock,& a little girl(mom) come on the dock.& its very cute and i think they hold hands or somthing.
Please tell me this movie exists and i didn't make it up. Thanks
