Gravity picked up the most Oscars at this year's Academy Awards, with a haul of seven prizes, mainly in the technical categories.

As well as the gongs for cinematography, film editing, visual effects, original score and director, Gravity was also honoured for sound mixing and editing.

The winners of those awards talked to Lizo Mzimba on the red carpet for the post Oscar's Vanity Fair party.
