There is another set of twins used, that is the security guard who gets a full house on the coffee machine. He meets his 'double' that is actually the t-1000, who 'pokes' him through the head. The actor duo are in a few other movies, including Gremlins 2, where they aren't trying to fool the audience, but just are twins.
