What We Did on Our Holiday is a 2014 British comedy-drama film written and directed by Andy Hamilton and Guy Jenkin. The film, starring David Tennant, Rosamund Pike, and Billy Connolly, was inspired by, but not related to, the BBC show Outnumbered.
Plot
Doug McLeod (David Tennant) and his wife Abi (Rosamund Pike) unite following a tense separation to travel to the Scottish Highlands for Doug's father Gordie's (Billy Connolly) 75th birthday. Gordie has terminal cancer so Doug's brother, millionaire Gavin McLeod (Ben Miller) has arranged a lavish party for him, inviting all the important people in the neighbourhood. Despite difficulties getting their three children, Lottie (Emilia Jones), Mickey (Bobby Smalldridge), and Jess (Harriet Turnbull), to leave the house, they hit the road, but find it congested and they are forced to stop overnight.
Lottie expresses her troubles with trusting her parents following their recent separation and lies to each other; it is revealed that Doug had an affair, which led to Abi moving out and taking legal proceedings against him. They are only travelling to the Highlands together to appear as a couple for Gordie, not wanting to upset him in his final months.
On arriving at Gavin's mansion, a tense rivalry becomes apparent between Doug and Gavin. Gordie, despite being extremely ill, is fun-loving and encourages his grandchildren, particularly Lottie, to let go of their troubles and enjoy life. While Gavin, Doug, Abi and Gavin's wife Margaret (Amelia Bullmore) make the final arrangements for the party, Gordie takes the three children to the beach. He reveals that he is descended from Vikings, a fact that Mickey in particular is excited about; he reveals his desire to be buried "the Viking way" by being cremated and sent out to sea. He believes this will stop arguments between Doug and Gavin. Later, while Lottie, Mickey and Jess are playing, Gordie dies peacefully.
