Finch was married three times. In 1943, he married Romanian-born French ballerina Tamara Tchinarova; they worked together on a number of films. They had a daughter, Anita, born in 1950. They divorced in 1959, after she discovered his affair with actress Vivien Leigh in California. He then married South African-born actress Yolande Turner (née Yolande Eileen Turnbull); they had two children together, Samantha and Charles Peter. During their marriage, Finch had an affair with the singer Shirley Bassey. Bassey had a daughter, also named Samantha, born in 1963; Bassey's husband at the time, the openly gay film producer Kenneth Hume, believed that Finch was her biological father. Finch and Turner divorced in 1965. In 1972 Finch married Mavis "Eletha" Barrett, who was known as Eletha Finch. They had a daughter together, Diana.
Finch's next three films saw him support notable female stars: Sophia Loren in Judith (1966), Melina Mercouri in 10:30 P.M. Summer (1966) and Julie Christie in Far from the Madding Crowd (1967). He was reunited with Aldrich for The Legend of Lylah Clare (1968). The Red Tent (1970) was an expensive international adventure film, with Finch as Umberto Nobile.
As announced in 2017, the US PGA Championship was moved from August to May, starting in 2019. The PGA of America cited the addition of golf to the Summer Olympics, as well as cooler weather enabling a wider array of options for host courses, as reasoning for the change. It was also believed that the PGA Tour wished to re-align its season so that its FedEx Cup Playoffs would not have to compete with the start of the NFL season in early September, since both United States broadcast partners (CBS and NBC) are NFL broadcast partners.
“Peter and the team offer professionally run, competitive golf at the best courses in the UK. It has been a great way for me to play the top venues under tournament pressure whilst meeting people I now class as friends. A tight ship is run too, with no questionable handicaps and scores, which are well within reason, picking up prizes is a refreshing change. Since my involvement from 2014, you can see the tour growing naturally year on year and given the schedule who can see it stopping. Every event is top class – and glad to be apart of it.”
