15) Zombieland ( 2009)
Much of Bill Murray's cameo in Zombieland was improvised. His hilarious and memorable death scene comes from much improvisation. His dying words, mostly unplanned, were said to Columbus, portrayed by Jesse Eisenberg, as he was mistakenly shot by the protagonist.
Dry and comedic, Murray declared how sorry he was to have played Garfield. It was an unexpected addition that was brilliant on its end and one that his co-stars weren't quite prepared for. What could have been a simple death scene is transformed by Murray's improvisation, turning it into one of the funniest and most quoted moments in the movie.
The cameo is one of the most memorable moments in Zombieland and brings surprise and some much-needed humour to complement the film's tone.
