In the clip, we see Alicia (and her mullet, eeew :S) crooning in a deserted warehouse, where she's being watched by none other than Pharrell. Yes, him again! There's also some amazing footage of the film itself and it looks awesome!
Sigh, and Andrew Garfield just looks to darn good in his Spiderman suit. That Emma Stone is one lucky girl.
Watch the funky clip below!
