I'll make this short and sweet, because I don't think I need a lot of evidence to convince people to see this movie. I'm sure everyone knows or has known someone who grates on every last nerve; the kind of person that causes groans and eye-rolls the instant they enter a room. You know that as soon as they see you, you're either going to have to bat away a verbal barrage or run the hell away as fast as possible. It's even worse when their only motivation is to get you to do something. You say no, but they don't care. Half-an-hour later, you're still repeating the same damn thing you said at the beginning of the conversation.
Sound familiar so far? Now replace whoever you're imagining in your head with Ben Kingsley, and instead of him trying to get you to cover for him at work, he's berating you about robbing a bank. He's bad news, but he won't go away until that "no" is turned to "yes." He's a nasty individual without a nice bone in his body, and he's screaming right in your face at the top of his lungs.
The film is Sexy Beast, and Ben Kingsley is Don Logan:
Don't worry, that's not the ending.
If that doesn't make you want to see Sexy Beast, nothing will. Especially since that scene is the essence of the entire movie. The heist itself is irrelevant to the central theme: It really sucks to have to deal with Don Logan.
Still, it's in your best interest to find this movie and watch it. Don't make me ask you again.
