Yes, it's the biggest night in the calendar for film and celebrities.

We've got all the snaps from the Red Carpet, but for now, here's the winners and losers from the 2015 Oscars. Overall, it was a pretty safe affair. Neil Patrick Harris' opening routine and subsequent gags throughout the night were fairly between the lines, as well as the winners being more or less as we predicted.

Ireland's Song of the Sea failed to win in the Best Animated Feature category, however, with American Sniper only snagging one Oscar in a technical category.

So, to the winners...
