Sellers's final performances were a series of advertisements for Barclays Bank. Filmed in April 1980 in Ireland, he played Monty Casino, a Jewish con-man. Four adverts were scheduled, but only three were filmed as Sellers collapsed in Dublin, again with heart problems. After two days in care—and against the advice of his doctors—he travelled to the Cannes Film Festival, where "Being There" was in competition. Sellers was again ill in Cannes, returning to his residence in Gstaad to work on the script for his next project, "Romance of the Pink Panther". At the urging of his friends, he made an appointment to undergo an angiogram at the Cedars-Sinai Medical Center in Los Angeles on 30 July 1980, to see if he was able to undergo open-heart surgery. Spike Milligan later considered that Sellers's heart condition had lasted for over 15 years and had "made life difficult for him and had a debilitating effect on his personality." Sellers's fourth marriage to Frederick collapsed soon after.
