Bequest to the Nation (U.S. title The Nelson Affair[1]) is a 1973 British historical drama film directed by James Cellan Jones and starring Glenda Jackson, Peter Finch, Michael Jayston and Margaret Leighton.

The New York Times found the film "thoroughly genteel", and wrote that Rattigan's dialogue was written "in the manner of someone regurgitating the cadences of a 19th-century schoolgirl's diary... Peter Finch plays Lord Nelson with a reserved passion that seems intelligently thought out but is not terribly interesting to watch, while Glenda Jackson seems to go at Lady Hamilton from the opposite direction.

"[1] Sky Cinema found the film "remarkable for the handsome Technicolor photography of Gerry Fisher and the brilliant production design of Carmen Dillon.

There are some touching moments, notably those involving Margaret Leighton as Lady Nelson, and vivid climactic battle scenes.

However, the two principals are not very well cast, and while Peter Finch struggles gamely to erase memories of Olivier's version of the role, Miss Jackson responds by stridently over-playing her hand as a sluttish Emma".
