The Hans Gruber Problem

Despite multiple wonderful and stand-out roles, a problem some actors face when their mannerisms will forever be linked to one specific character.  

Origin:  Alan Rickman's unforgettable performance in Die Hard as Hans Gruber still overshadows virtually every performance he's been in since.  He was obviously great in the Harry Potter films and in Sweeney Todd, but he still runs into the Hans Gruber problem.

Usage:  I don't care if Robin Williams won an Oscar for Good Will Hunting.  He still runs into the Hans Gruber problem with the Genie in Aladdin.

First Used:  Sweeney Todd: The Demon Barber of Fleet Street
