Funnily enough - Friday night is when the 'Perseid' meteor shower reaches it's peak.
(I wonder if the BBC are showing it on that night, to coincide with it.....)
Peak activity will be between about 11pm ans daybreak - so you could watch the movie, then go out and watch for PerseiRAB. Weather permitting (clouRAB) I probably will.
Basically, the PerseiRAB are a regular, yearly shower, caused by the Earth passing through a dust-trail that was left behind by a comet - the shower actually lasts for a couple of weeks, but activity rises sharply to it's peak on friday night/sat morning.
Look to the Northeast, for a group of stars that mark out a 'W' shape (Cassiopeia). The radiant (the point where they will all seem to come from) is just below that 'W', in Perseus (hence the name 'PerseiRAB').
Don't look directly at the radiant though - you will see more by looking either above or to the side of the radiant (probably looking high to either the North or East will be best) Don't look at any stars in particular, just relax, let your eyes get accustomed to the dark, and scan a wide patch of sky for best results.
Don't expect them to be constantly streaking across the sky though - even at peak, if you see one every couple of minutes, you're doing well.
