On set with Ol' Blue Eyes: Never-before-seen candid pictures show Frank Sinatra goofing around, having a smoke and posing with Audrey Hepburn and Grace Kelly

Never-before-seen pictures of Frank Sinatra have come to light showing how he rubbed shoulders with the likes of Audrey Hepburn and Grace Kelly on film sets.

Even though he is more commonly known as one of the most influential crooners of the 20th century, he was also a talented and prolific actor who built up an impressive film career.

Now a new book has been released to mark the centenary of his birth and it is crammed with charming and often informal shots of him in between takes with some of the biggest A-list stars of the era.

About a third of the photos in this book came from his own collection.

He said: 'On the occasion of the centenary of Sinatra's birth I really wanted to cement his legacy as one of the great motion picture actors.

'We all know Frank Sinatra as one of the most extraordinary singers of the 20th century, but his role as an actor was treated as secondary to that and I really felt he was one of the best in the industry.

'The amazing thing about Frank is he was able to adapt into many different genres. He did dramas, musicals, comedies.

'The book also has wonderful essays written by his three children.I've known Nancy's daughter Amanda for years, I've always wanted to do this book and I asked her if she thought her family would write something.

'The thing I was happiest with was being able to find so many pictures that haven't been seen before, and from some of his bigger titles.

'The photographs came from private collections, news services, film studio archives and my own archive.

'I really wanted to make sure all the images came from original sources, negatives and transparencies, and in many cases we were able to digitally restore the colour back to its original brilliance.

The cover of the new book on Frank Sinatra, which features never-before-seen pictures from his extensive film career 

'Most of them are unseen - they came from troves of negatives that had never been developed before.

'Back in the 1940 to 60s people didn't appreciate how important these negatives were.

'A photographer would visit a set and send original negatives to newspapers all over the world.

'These pictures would stay in filing cabinets or boxes for years but often they'd eventually be destroyed so I've been quite lucky to find these unseen ones.'

The book will be published by Amberley Books priced £17.99.
