John Travolta has said his late wife Kelly Preston was "very proud" of her final film, which has been released after her tragic death.
The Grease actor, 67, took to his Instagram account on Friday to share a trailer for Off The Rails, which Kelly filmed in 2019 and was released in cinemas this week.
Kelly died last summer after battling breast cancer, which she had decided to keep private. She was 57-years-old.
In his post, John wrote: "Off the Rails starring Kelly Preston.
"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!"
His daughter Ella Travolta, 21, who he shared with Kelly, commented on the post with three love heart emojis.
Off The Rails also stars Jenny Seagrove, Sally Phillips, Elizabeth Dormer-Phillips, Ben Miller, Franco Nero and Judi Dench.
Kelly plays an American named Cassie, one of three friends in their 50s who go on an inter-rail adventure across Europe to celebrate the life of their friend who has just died.
The friend left the group four train tickets, with the condition that they take her teenage daughter with them in her absence.
Off The Rails began shooting back in February 2019, and was filmed between Mallorca, Barcelona and London.
Kelly was diagnosed with breast cancer just months before filming began.
She decided to keep her illness private, and it wasn't revealed until after she died.
John confirmed his wife's passing in a heartbreaking statement that he shared in July last year.
A representative said in a statement at the time: "On the morning of July 12, 2020, Kelly Preston, adored wife and mother, passed away following a two-year battle with breast cancer.
"Choosing to keep her fight private, she had been undergoing medical treatment for some time, supported by her closest family and friends.
"She was a bright, beautiful and loving soul who cared deeply about others and who brought life to everything she touched.
"Her family asks for your understanding of their need for privacy at this time."
John then shared his heartbreak on Instagram, writing: "It is with a very heavy heart that I inform you that my beautiful wife Kelly has lost her two-year battle with breast cancer.
"She fought a courageous fight with the love and support of so many.
"My family and I will forever be grateful to her doctors and nurses at MD Anderson Cancer Center, all the medical centers that have helped, as well as her many friends and loved ones who have been by her side. Kelly’s love and life will always be remembered.
"I will be taking some time to be there for my children who have lost their mother, so forgive me in advance if you don't hear from us for a while.
"But please know that I will feel your outpouring of love in the weeks and months ahead as we heal. All my love, JT."
