The new George Clooney-directed film Suburbicon takes place in an idyllic 1950s suburb where a family man (Matt Damon) hires two hitmen to stage a home invasion to get rid of his wife (Julianne Moore), but—shockingly—things go awry. In the video above, Glenn Fleshler and Alex Hassell, who play the two hitmen, tell how they prepared for all their onscreen dirty deeds.
