A lawyer has said the reported £50m actor Harrison Ford will pay ex-wife Melissa Mathison is not the highest in Hollywood history.
Ford and Mathison were married for 18 years
It follows weekend reports the 61-year-old actor will pay £50m, which includes shares in royalties earned from film made during their marriage.
Mathison, 53, who wrote the script for ET, was married to Ford for 18 years and had two children with him.
Ford has been dating actress Calista Flockhart for the last two years.
Indiana Jones and the Last Crusade was also made during his marriage to Mathison, as was 2002's K19: the Widowmaker, for which the actor was paid $25m (£13.8m).
Movies Ford made included The Fugitive and Air Force One.
The reported divorce settlement is bigger than the reported £46m between Tom Cruise and Nicole Kidman in 2001, but it is not as large as the $100m settlement that Steven Spielberg had to give wife Amy Irving in 1989 when they divorced.

Ford was granted his divorce earlier this month. Mathison has applied for custody of the couple's two teenage children.
"The unusual thing about this divorce is there wasn't a pre-nuptial agreement. They were less common when they married, but they were still around," said lawyer Lisa Fabian Lustigman.
She said that most high-profile marriages in the US now would almost certainly have a pre-nuptial agreement.
The settlement, Ms Fabian Lustigman also said, may also be so high because of the length of the marriage and the fact the couple had two children together.
"From an English law point of view, had the case been decided over here, Ms Mathison's contribution would be treated as equally important and weighty as his contribution as the breadwinner," Ms Fabian Lustigman said.
The actor was also previously married to Mary Marquardt for 15 years, divorcing her in 1979.
