John Travolta said his late wife Kelly Preston was "very proud" of her final film role.
Off the Rails, which was released in the UK and Ireland on Friday, is the actor's last picture to be released following her death from breast cancer last year at the age of 57.
Travolta shared a trailer of the film to his Instagram, writing: "Off the Rails is Kelly's last film- she was very proud of it and of all of the wonderful talent that she got to work with in it.
"It is available in UK and Ireland theaters starting this Friday July 23rd! @offtherailsfilm @bklproductions."
The film sees a group of friends in their 50s head off on an inter-railing adventure around Europe following the death of a friend, whose teenage daughter goes with them to fulfil her dying wish.
It also stars Jenny Seagrove, Sally Phillips, and Judi Dench.
Preston had kept her two year breast cancer battle private, with it not being shared until after her passing last July.

Travolta has continued to publicly remember his wife, including celebrating Preston on her birthday and Mother's Day.
Ella also marked the release of Off the Rails on her own Instagram page as she said her mother had "very much enjoyed" the time she spent making the movie.
