Earlier in the Indiewire interview, Guy Ritchie attributed The Man from U.N.C.L.E.’s commercial failure to its poor release date, August 24, but he was clearly pleased to learn that the movie has a passionate fanbase.
Critically The Man from U.N.C.L.E. performed decently when it was released in 2015, ranking at 67% among critics on Rotten Tomatoes and earning a 73% Audience Score.
Commercially, on the other hand, it underperformed, making only a little over $109 million of a $75 million budget.
Presumably learning how little money it made had influenced how he thought it was received by audiences.
