Seth Rogen might just win the award for all-time great drug-tripping performance in this very funny holiday film from director Jonathan Levine. Rogen and Anthony Mackie play Isaac and Chris, best friends to Ethan (Joseph Gordon-Levitt), who lost his parents when he was young. Since the death of Ethan’s parents, the three have gathered every Christmas Eve to celebrate together in rambunctious fashion. In what is supposed to be their final Christmas Eve journey together—Isaac is having a baby, and Chris is a famous football player—Ethan scores tickets to the wildest party of the year. Rogen spends the majority of the film tripping balls after consuming mushrooms, pot and cocaine—gifts from the wife—and he should get some sort of drug performance Oscar for what he does in this movie. Michael Shannon shows up as one of the strangest drug dealers in cinema history and, lord knows, there have been some strange ones. The film gives us the greatest gift of all with Lizzy Caplan as Ethan’s love interest because, let’s face it, she’s awesome. Miley Cyrus makes a fun cameo as herself, while somebody else who I shall not reveal makes a surprise appearance and steals some scenes. This one is a nice addition to the holiday movie canon, and Rogen solidifies himself as a stoner hero.
