Val Kilmer is shown breaking down in the trailer for his new movie Val as he admits he struggles to talk and be understood since having a voice box fitted.
The 61-year-old actor - who was diagnosed with throat cancer in 2014 - is sharing years of personal home movies to tell his life story in the new documentary film, which is premiering at the Cannes Film Festival.
Kilmer shared the trailer on Twitter saying: "It feels like yesterday and yet it has been a lifetime. As I write this, my documentary is getting ready to premiere at Festival De Cannes. And as grateful as I am for being selected with this high honour, I look forward most to sharing my life's story with all of you.

"As a lifelong filmmaker it thrills me to say the film will be in theatres July 23. And as a person who also enjoys getting cosy, I'm possibly more happy that it will be on @PrimeVideo Aug 6. Here's to giving every day the opportunity to be the most beautiful of your life."
The voiceover declares: "I've lived a magical life and I've captured quite a bit of it.
"I was recently diagnosed with throat cancer. I'm still recovering.
"It is difficult to talk and be understood, but I want to tell my story more than ever."
A montage of footage shows Kilmer in tears and then later talking with a voice box, saying: "I've tried to see the world as one piece of life."
His rasping words are subtitled.
A voice box device is normally battery-operated and can implanted or held against the throat to help the user produce sound if they have had their larynx removed for medical reasons.
Kilmer was diagnosed with throat cancer in 2014. He went public with the diagnosis in 2017 after initially denying he was ill.
He began his movie career in 1984 and over the years has starred in hit movies including Top Gun, Willow, Batman Forever, Jim Morrison biopic The Doors and Heat, among numerous others.
Kilmer and Tom Cruise are this year set to appear in Top Gun: Maverick, a sequel to the 1986 action movie.
