MEMBERS of the Royal Navy Submarine Service surfaced on the Clyde for an extra-special advanced showing of Hollywood movie Hunter Killer.

More than 200 submariners were invited by Lionsgate Entertainment to watch the film at a specially organised viewing at HM Naval Base Clyde.

The Armed Forces premier took place October 19, the day before the film was released to the general public,.

The action-packed movie, which stars Gerard Butler and Gary Oldman, tells the story of a US Navy Hunter-Killer submarine, called into action to rescue the Russian President when he is captured by his own Defence Minister during a visit to a Russian Naval Base.

Butler plays submarine Commander Joe Glass who is sent into Russian waters to help rescue the President and prevent a global conflict.

The Paisley-born actor, who is a known supporter of the armed forces, was keen real submariners had a chance to see the film and even recorded a special message for them which was played before the movie.

“We were thrilled when Lionsgate got in touch with us and said that they and Gerard Butler would like to give us an advanced showing,” said Rear Admiral John Weale, Head of the Submarine Service.

“As you can imagine there was quite a lot of excitement among the submariners at having a chance to see Hunter Killer before it was released. During a submarine patrol, movie nights in the mess become important. It’s a way of relaxing between watches and, as you can imagine, there’s much debate about which are the best submarine movies.

“I’m glad to say they gave Hunter Killer the thumbs-up. We were particularly thrilled that Gerald Butler went to the effort of filming a message.

"It was a special occasion for the Submarine Service.”

During his address the actor said: “I think the work you all do is incredibly inspirational and I want to thank you for that.”
