Kenneth Branagh has urged cinemagoers checking out a SIR Michael Caine film to visit the toilet before the opening credits - because the veteran actor hates it when anyone leaves their seat during one of his movies. The British filmmaker, who recently directed Caine in a remake of thriller Sleuth, reveals the star takes it personally if anyone has to hit the restroom during a premiere or a special screening of one of his films. Branagh reveals, "He's at the back checking and one of Michael's guides for how the movie's going is if anyone gets up to go to the loo - he doesn't like that. "All I can say is if you're at a premiere and Michael Caine is at the back and he's watching and you go to the loo, get back to your seat very quickly. "You get to the point where you think he's gonna go to the bathroom and bring them back."
