VIDEO Robert Downey jr really wants you to vote

Tomorrow's a big day in America, in case you didn't know and everyone is being urged to get out and vote and make their voice heard.

Robert Downey jr and his famous friends are really interested in you getting out to vote too, but some of them want it because you'll get to see Mark Rufallo naked...

These Save the Day videos are the work of none other than certified genius Joss Whedon and while the content couldn't be more political the message is clear - just get out and have your say.

It's a bit of a tricksy thing getting these kind of folks involved but it's also Whedon's first original directed work in years, so we're not complaining.

We really don't think we're going to get to see Mark's hammer though.
