I can imagine what this brief might have looked like:
Main Message: Orange offers it's customers two for one movies on Wednesday's
Strategy: Show consumes why being with Orange is better than any other teleco provider
Mandatories: Explain the new service, show it, talk about Orange, show friends having fun together, 60 second spot, tag at the end, etc
Not a walk in the park, by an means. But the creative team worked with it and created a spot that is upbeat, memorable and fun. And as an added benefit to the client, it's easy to retain the key message.
Next time you get a brief that seems boring or complicated, remember this spot and think about all the cool stuff you could do with it.
Nice work Fallon and Orange.
