The three 10-second executions feature extreme situations where a sore throat could prove life-threatening. In one a lumberjack tries to warn of a falling tree, another has a parachutist stuck up a tree unable to call for help, while the third sees a waiter dragged off by a monster.
The national TV campaign launches this week and runs to the middle of February.
Alice Hunt, communications director at GlaxoSmithKline, said the aim of the spots was to appeal to a 16- to 34-year-old audience who wanted a 'no-nonsense' product. "We feel the humorous and original executions created by Grey and the Beechams product team achieve that perfectly. They're extremely impactful," she said.
Grey London's creative director Dave Alberts said the work was "an example of what can be achieved with a good client-agency relationship and a shared, powerful creative vision".
The spots were written by Colin Booth and Ben Stiltz and directed by Happy. Media buying was through Mediacom.
The Max Strength lozenges contain a combination of anaesthetic and anti-bacterial ingredients to tackle the seasonal sore throat.
