Terry is distracted by some off-camera disturbance around the 22 minute mark, laughing and stopping to look behind him. However, the source of his distraction is not shown.
Terry speaks off mic around the 6 minute mark.
Terry announces who isn't playing in the game 24 minutes in, with the camera centred on Arthur Askey. When Terry says Isla St. Clair's first name, the camera jolts slightly to the side and then repositions, as if the cameraman had planned to pan along to St. Clair, but decided against it.
When talking to the contestant in the second "Supermatch Game", Terry stops and says "I'm sorry, I just spat past just you there", indicating the direction of the saliva with his hand.
There's a slightly awkward moment around the 17'50m mark, where Diana Dors encourages David Hamilton to show an alternative answer he'd written down. Terry Wogan, seemingly suspecting it was inappropriate, says "no", before urging Dors to "come on now".
