In reply to biscuit:
Hulots holiday is going to have to be researched i think.
The plank is an excellent suggestion as is anything with Gene Wilder/Richard Prior, Steve Martin etc.
The Lady killers could be a corker.
Blazing saddles is out due to my brother in law who will give a running commentary all the way through and probably try to rewind it to watch bits again :0)
Wife not keen on airplane/top secret type stuff - no sense of humour i'm afraid :0(
The money pit could be a contender and one that we hadn't thought of.
What about Cannon Ball run or Smokey & the Bandit ?
Anyone seen the Morecambe & Wise films ? My wife and i thought they were hilarious but others may not.
