This is a film we saw on very late night tele years ago but we can't remember what its called.It had a dead guy who started walking whenever music was played-he walked in a funny way with his head back (coz he was dead,obviously).There were 2 guys who were controlling/following him because the dead guy was going to lead them to his fortune.There was also a 'baddie' who was freaking out about spotting the dead guy everywhere.At one point the baddie was on a submarine and he looked out of the window to see the dead guy walking along the bottom of the ocean.
That's about the sum of what we remember but we'd love to know what the film was so we can watch it again as its stuck with us.Does anyone know?

Probably Weekend at Bernie's II (http://www.imdb.com/title/tt0108539/).

Excellent! Just went and checked title on Amazon and that's definitely the one.Its been bugging us for years! Thank you very much.We are happy now!
