Other regulars included Thelma Carpenter as Corie's mother, Mable Bates, Harry Holcombe as Mr. Kendricks, Vito Scotti as Mr. Velasquez, and Nipsey Russell as local pool hall owner, Honey Robinson.
Marshall's later co-star of the mid-1970s television success Laverne & Shirley, Cindy Williams, appeared on the sixth episode, which aired on October 29, 1970, titled "The Marriage Proposal".
When Barefoot in The Park premiered on Thursday, September 24, 1970, at 9 p.m., it was the lead-in program for another series based on a Neil Simon play, The Odd Couple, which debuted immediately afterward.
Despite the fact that it never placed in the top 30 television shows, The Odd Couple had a five-year run on ABC and won Emmy Awards for its two stars Tony Randall and Jack Klugman.
The show was produced by William P. D'Angelo, and various episodes were written or directed by much of the same team that had developed The Odd Couple (Jerry Paris, Harvey Miller, Bruce Bilson and Garry Marshall).
