Continuity mistake: When the XT-70s are launched, you see Polaris A1 missiles (single warhead) being launched, In the next shot you see Polaris A3 missiles (multiple warheads) flying.
Continuity mistake: When Bond's bike is trapped in the tunnel, two white and black cars stop behind him, and two baddies with chains exit. When the angle changes, Fatima exits her car and everything's repeated: the two cars come to a stop and the baddies exit again.
Continuity mistake: During the credits Bond jumps into a window. From the outside, the window to the left of where Bond jumps through, is complete; from inside the house the window is shed to pieces.
Continuity mistake: Right before Bond grabs a bike and chases Fatima Blush, he is eating an apple which swaps from yellowish-red to fully yellow, between shots.
Continuity mistake: While riding the bike, Bond's helmet swaps from bright to matte between shots.
Continuity mistake: When Bond and Domino jump into the water from Palmyra, the Arabs are shooting at them with rifles from the wall. The submarine starts shooting at the top of the wall. But in the second shot of the submarine it is very far in the background - shooting at a point in the wall which is very very far from where Bond and Domino are in the water.
Chosen answer: Neither is a professional dancer. Having studied dancing some thirty years before does not mean someone has retained the same level of skills. As you mentioned, Connery was in his 50s by that time.
