Zack Sharf Digital News Director Thirteen years later and Christopher Nolan is still being hounded with questions about the ending of “Inception,” his acclaimed 2010 action thriller about a group of criminals who pull off a dream heist. The ending is notorious. Leonardo DiCaprio’s Cobb has completed his task and returns home to his children, but the film lingers on his spinning totem top as it begins to wobble. Cut to black. If the top spins indefinitely, Cobb is still dreaming. If it falls, Cobb is awake in the real world. Moviegoers have spent over a decade debating whether or not Cobb is awake or dreaming at the end of “Inception,” but Nolan recently said on the “Happy Sad Confused” podcast that such debates are missing the ending’s real takeaway: Cobb doesn’t care.
