Rudolph Bucko, whose given name was Rudolph Bouckou, was a skilled cowhand hailing from Yakima, Washington. Alongside his brother Roy Bucko, they embarked on a journey south, eventually finding themselves working on the vast western ranges of Hollywood. Although neither brother was frequently credited, Rudolph was occasionally billed under his nickname "Buck'Bucko," and in a few instances, he was credited as Rudolph "Buck" Bucko.
As a result of the two distinct billing names used in his limited credited roles, trade journals, particularly the annual "Film Daily Year Book," carried listings for both Rudolph Bucko and BuckBucko, despite both names referring to the same individual. Due to the limited and inaccurate research conducted by some sources, a misconception arose that there were three Bucko brothers. In reality, Rudolph Bucko was one of the two brothers who worked in an impressive array of over 200 sound-era westerns and serials.
Rudolph and his brother Roy Bucko were mainstays at Columbia and Universal during this period, appearing in numerous films together, including many Republic productions from 1935 to 1952 or so. While both brothers were present in most of the films they worked on, there were instances where Roy appeared in more films than Rudolph, with a total of at least 55 additional credits to his name.
