Continuity mistake: When Marty bangs open the crane's cage, he is about a foot away from where he had been in the previous shot, when the crane pecked him on the rear end. To achieve the latter he had to be fairly close to the bird, but to accidentally open the cage easily by pushing at it with his cane, he had to be standing farther away, or it wouldn't have worked. He moves that distance from shot to shot and it just wouldn't have happened in real time.

Answer: It equals the record of James Arness of "Gunsmoke" for the actor who's played the same part on TV NOT in a soap opera. If you include soaps there are two main contenders - William Roache, who's been playing Ken Barlow in "Coronation Street" in the UK since 1960. Don Hastings has been playing Robert Hughes in US soap "As the World Turns" since 1960 as well.
