Sometimes people like to render metaphors literally, and in the case of The Mummy, the metaphor "take a licking" results in the Mummy (Sofia Boutella) laying her tongue on Nick Morton (Tom Cruise). Although, let's be honest, Tom Cruise is always just playing Tom Cruise.
Despite what it may look like at the start, this is not a trailer for Mission: Impossible 6. Sure, there's Tom Cruise, on a plane, in the middle of a huge action scene. But once the ancient evil lady starts walking around, it's obvious this is something quite different. This is The Mummy.
