Bearded and scruffy-looking, William Merrill McCormick became one of the busiest character actors in B-Western history. Beginning his screen career in the late 1910s, McCormick excelled at playing unshaven henchmen, rustlers, stage robbers, and a host of other less-than-desirable prairie varmints. Rarely the main villain, he could usually be spotted sneering in the background alongside such fellow bit part players as Jim Corey, Bill Gillis, and Al Ferguson. Taking time out to direct good friend Marin Sais in a couple of very inexpensive oaters in 1923, McCormick kept up a hectic acting schedule that lasted well into the television era. He died of a heart attack right after finishing a scene for the television series The Roy Rogers Show.
