He joined the Los Angeles film community in 1918 with Universal's Jewel comedies.

"[1] He played character roles in comedies and westerns into the 1920s, signing with Hal Roach in 1923 and then Mack Sennett in 1924.

In 1927 Loback was hired by Weiss Bros. to co-star with Snub Pollard as a fat-and-skinny comedy team, patterned after the new Laurel and Hardy partnership.

These low-budget films were obvious imitations, with Pollard and Loback using Laurel and Hardy's derby hats and some of their situations.

He appeared in the federally funded WPA plays "If It Pleases the Court" (1936)[2] and "Roaring Girl" (1937).
