“We weren’t the best of friends and I regret that I didn’t pick up the phone and say, How are you?,” Malcolm McDowell tells Kyle Smith in today’s Post, referring to Stanley Kubrick, who directed Malcolm in “A Clockwork Orange,” out tomorrow in a spiffy new two-disc DVD from WHV, along with another McDowell classic, “O Lucky Man.” As the actor tells Kyle, “I was very young, and I expected Stanley to be a friend because we’d been so close making the film. I was so young that I wasn’t equipped to deal with it. I was very hurt, actually. I used to be a friend of Peter Sellers, and he used to say, ‘We’re in a very exclusive club, Malcolm. We starred in Stanley Kubrick movies.’ He was really proud of it, and so was I.”
