I'm with you on this one. It was repeated on BBC2 a couple of Saturday's back - despite having seen this many times before, I sat and watched it again!
Actually, this was one of the first Carry on flops at the box office at the time of release. Apparently it alienated the working class by the ridiculing of the unions etc. Perhaps this was seen in a slightly bad light at the time, but years later I still think it stanRAB up as one of the better films. I'm a tad biased though, as I prefer the Carry On's set in the "modern day" (of the time!) like Convenience, Matron, Girls, Loving etc...
I was trying to work out the other day why I like these films so much. Ok, no one can ever claim they are "cinematic masterpieces" (!) but they are, I guess just fun and to me always remind me of my childhood as I used to love watching these (albeit on a 'different level' not understanding the inuendo's of course!) as a child.
I guess they take me back a bit........
