Which actor played Jerry’s father Morty in later Seinfeld appearances? Barney Martin.

Barney Martin played Jerry’s father Morty Seinfeld in the later appearances of the character on Seinfeld. Martin first appeared as Morty in Season 2’s “The Pony Remark” and continued in the role through the series finale in 1998.

Morty was originally played by Phil Bruns in the Season 1 episode “The Stake Out.” Larry David and Jerry Seinfeld wanted Morty to have a harsher, more opinionated personality, so Martin replaced Bruns and became the actor most associated with the role. The recasting is why both actors can be correctly linked to Jerry’s father, but Martin is the answer when the question specifies later appearances.

Morty’s recurring storylines often involved money, thrift, retirement, and his volatile but affectionate relationship with Jerry. His signature disputes over expenses helped establish the Seinfeld parents as comic extensions of the show’s everyday-observation style.

Before Seinfeld, Martin had worked as a New York City police officer and appeared in films including The Producers and Arthur. He also originated Amos Hart in the 1976 Broadway production of Chicago.
