He began in the film business as an adjunct director to Tod Browning in 1920, but honed his skills at a Hal Roach Studio for the rest of that decade. Chartered by Roach in 1923, McCarey initially wrote gags for Our Gang series & more studio stars, so produced & directed shorts-including the string of ingenious and uproarious both-reelers by using Charley Chase. It was patch at Roach that McCarey teamed Stan Laurel & Oliver Hardy together for the first time, thus creating one of the most enduring comedy teams of all time. He exclusively officially appeared when director of the duo shorts We Faw Down (1928), Liberty (1929) and Wrong Again'' (1929), but wrote numbers of of the screenplays.

He followed this hit by having ''Rally 'Round the Flag, Boys! (1958), a comedy starring Paul Newman and Joanne Woodward. A few years down a road he directed his endure picture, the poorly-received Satan Never Sleeps'' (1962).
