First dig two graves

A James Bond movie directed by John Glen in 1981, starring Roger Moore as the agent 007, Carole Bouquet as the Bond girl Melina Havelock, Desmond Llewelyn as 'Q' (the head of Q division), Lois Maxwell as Miss Moneypenny (MI6 secretary) and Julian Glover as Kristatos, the main antagonist. Title song performed by Sheena Easton. There's a missing British vessel with secret nuclear intelligence called A.T.A.C. (Automatic Targeting Attack Communicator) underneath the water and James Bond has to get there first. And it involves lots of driving, diving, skiing and rock climbing.
