This Friday, Mega Shark Vs Giant Octopus explodes all over our cinemas.

We've already seen it so you don't have to, but since it joins a long and not always illustrious list of "versus" movies, we thought it was worthwhile to look back at the maddest match-ups from the past in honour of this crazed nonsense...

Freddy Vs Jason (2003)

The Fighters: Dream demon and former kiddie fiddler Freddy (in the shape of original brand Krueger, Robert Englund) goes up against masked monster Jason Voorhees.

Freddy's original idea, of course, was to use Jason to unleash havoc on the local teen population. But his plan goes awry when the hulking brute decides he's going to be top dog.

What Started The Fight? Horror movie audiences had been awaiting this sort of duel for a long time and New Line duly obliged, bringing together the two titans.

It's a madcap affair, full of in-jokes and all the chaos you could hope for.

The Loser: Anyone awaiting Freddy Vs Jason Vs Ash - with New Line intent on relaunching both Friday The 13th (already out) and A Nightmare On Elm Street (coming next year with Jackie Earle Haley in the striped jumper), there's not much chance of seeing it before Bruce Campbell is too old to run around as Ash.

There's a comic based on the idea, but no sign of a movie. Yet.

Oh, and Freddy loses in the movie itself when Jason impales him on his arm and the kids cut his noggin off.
