Harry Potter turns 33 today. That's way older than we all thought he was, right?

The best interviews either confirm something that viewers have always hoped to be true or surprises them utterly; Emmanuelle Riva does both. Of course she is too tired to attend the BAFTAs; of course she is happiest when she is working.

Crumbling Time-Prince Jude Law wants the world to know he's perfectly happy to at long last to look like a disgusting skin monster just like everyone else.

Snow White & the Huntsman has several cool tricks up its ornately designed sleeve, but the coolest one of all is its focus on its wicked queen's existential crisis. That is, after all, what's always driven the action of this oft- and increasingly told tale – the aging queen's savage jealousy of younger beauty is what forces Snow White away from her rightful castle, into the cabin of seven dwarves. It's what almost kills our protagnoist and it's what unites her with her true love, a prince.
