Michael “Mickey” Goldmill was portrayed by Burgess Meredith in the Rocky film series, in which he was nominated for the Academy Award for Best Supporting Actor for his performance in the first film, as was his co-star Burt Young. The character’s gravelly voice, intense demeanor and popular catch phrases helped make him highly recognizable as well as a common source of parody and satire in pop culture. 
Mickey may be based on Charley Goldman. Both were bantamweights, had Jewish ancestry, and have similar sounding names. In addition, Goldman was the boxing trainer of Rocky Marciano, on whom Rocky Balboa is based. Goldman trained Marciano in many ways similar to how Goldmill trained Balboa, such as tying their ankles together with string to teach them to spread their feet at the appropriate width. Goldman was (again like Goldmill) well known for making wise remarks (ex. “A lot of people say Rocky [Marciano] don’t look too good in there, but the guy on the ground don’t look too good either.”).
