Too right!
It's a superb British thriller, and one the best films to come out of the '70s (which is saying a lot!)
I first saw it on the old Studio Canal DVD release almost 10 years ago now, which I'm betting is a lot later than some people on here!
I would have loved to see it at the cinema on release, but alas, it was made 10 years before I was born!
The infamous shock ending was completely mind-blowing on the first watch, and I immediately had to go back and watch it all again, trying to pick up clues and information I may have missed tthe first time around.
The tense well-written plot and beautiful cinematography makes this a timeless classic in my eyes - roll on the Blu-Ray!
(And yeah, Christie and Pleasance were definitely into each other.
