Robert De Niro in Cape Fear

After Brando, De Niro is the most famous actor to have employed the method approach to his characters.

Cape Fear saw him pumped up like a middle weight boxer, while Raging Bull saw a weight gain that left him looking like anything but a fighter.

In fact, it was Raging Bull that set the record for the most weight gained by an actor for a role - a stunning 60 pounds.

Then of course, there was The Untouchables, which involved another 50 pounds worth of weight gain.

De Niro - the king of the weighty actors.
