Hello be first time user here... My question is... There's a movie I watched about a couple driving in a car at night and hit a person and tries to cover it up I believe the couple is richa and lives in a big mansion and things start to get out of control... could someone help me out? Thanks

This sounds like the movie Bonfires of the Vanities to me.

Are you sure it's not a TV series...

"The Riches"... starring, Eddie Izzard and Minne Driver

This was about a couple whilst driving came across, I think it was 2 bodies.

What happened was, the couple driving stole the bodies identities, then occupied their house posing as them!!

I think Orphan is correct on this one. I totally forgot about the Riches TV show.
