Cera collaborated with Chilean filmmaker Sebastián Silva on two films in 2013 – "Magic Magic" and "Crystal Fairy & the Magical Cactus" – both of which were filmed in Chile and premiered at the 2013 Sundance Film Festival. He spent "five hours a day learning Spanish" for "Magic Magic". Cera was featured most prominently in "Crystal Fairy", in which he starred as a self-absorbed man travelling Chile with a woman named "Crystal Fairy" (played by Gaby Hoffmann) while bearing a cactus. Along with Reggie Watts, Tim & Eric, and Sarah Silverman, Cera created the web-based comedy YouTube channel Jash in March 2013, where he has posted short films which he directs and/or stars in. These films include the comedy-drama "Gregory Go Boom" (2013), in which Cera played a paraplegic man, and his directorial debut "Brazzaville Teen-Ager" (2013), co-starring Charles Grodin as his sick father. He played an exaggerated version of himself in the apocalyptic comedy film "This Is the End", which was released in summer of 2013 and featured his "Superbad" co-stars Jonah Hill and Seth Rogen. Throughout 2013, Cera also appeared on "Burning Love", a web spoof of reality dating competition shows, and on an episode of "Drunk History" as John Endecott. Cera had previously played Alexander Hamilton in a comedic retelling of Hamilton's duel with Aaron Burr on the show's first episode as a web series in 2008 before it was adapted into a television show.
