Gerard Butler has long been a staple of the action genre, and it seems as if he’s only leaned harder into this area of his career over the last decade or so. After becoming a big name due to movies like Reign of Fire (2002) and 300 (2006), Butler appeared in a handful of exciting action flicks, including RocknRolla (2008), Gamer (2009), and Machine Gun Preacher (2011). It was in 2013, however, that Butler’s action hero persona really evolved.
