Little Brother feels like a throwback to brainrot comedies from 2000s and 2010s, like Step Brothers, Due Date, Bheja Fry, Due Date, and a bit of Mujhse Dosti Karoge (whose central premise is taken from, believe it or not, the 1897 Edmond Rostand play titled Cyrano de Bergerac). Directed by Matt Spicer and written by Jarrad Paul and Andrew Mogel, the movie starts with Marcus escaping from Renaissance Recovery to reunite with his “brother,” Rudd.
