Young and Florence Rice in prominent roles. She starred opposite Bela Lugosi in The Devil Bat. The cult film of the horror film genre is a Poverty Row production released by Producers Releasing Corporation. In the movie, Lugosi breeds giant bats to attack people. Her final appearance on film was an uncredited role as the Duchess of Park Avenue (Manhattan) in 1984's The Cotton Club. Theater Kaaren stepped into the character usually played by Ann Thomas in a Broadway presentation of Chicken Every Sunday. Staged in September 1944, Thomas left the production to go to Hollywood. In July 1946, Kaaren's elder son, Brewster, was in the play with her as an eight-month-old. She was also joined by her husband, Sidney Blackmer, on stage at the Bucks County Playhouse in New Hope, Pennsylvania. In April 1953, the Blackmers starred in Glad Tidings in Atlantic City, New Jersey. A month later, the show moved to the Quarterback Theatre, also in Atlantic City. In 1959, Kaaren appeared in The Royal Family at the Hinsdale Summer Theater in Chicago, Illinois. Linda Darnell starred; Karyn Kupcinet and Stuart Brent were also in the cast. The theme was a famous family of the American stage. Personal life Kaaren married stage and screen actor Sidney Blackmer on June 13, 1943, in a civil ceremony in Santa Ana, California. Raquel Torres was a witness at the wedding. Blackmer was married previously to Lenore Ulric. By this time, Kaaren was under contract to Metro-Goldwyn-Mayer. The marriage was a turbulent one from the outset. The couple separated in September 1943 and Blackmer instructed his attorney to file for divorce in October, but the couple remained together until Blackmer's death in October 1973. The marriage produced two sons, Brewster and Jonathen. The Blackmers had lived in his family home in Salisbury, North Carolina, until it was damaged by fire in 1984. Afterward, she resided in a rent-controlled Manhattan apartment at 100 Central Park South. According to her obituary, real estate developer (and later the 45th president of the United States) Donald Trump bought the building and threatened to evict all the tenants and tear it down to build something more lucrative. Kaaren's apartment was assessed at $750,000, but she refused to budge, and, in 1998, a court ruled that Trump could turn the apartments into condos, but had to allow the rent-controlled tenants to remain. She was, therefore, given $750,000 compensation.
