While this scene is non-canonical, the orcs' ability to overcome sunlight is.
The above scene never occurs in the books, the closest we get to something like that is the Goblins of the Mountains chasing Bilbo out of the hills, into the trees, in daylight.
Of course they soon came down after him, hooting and hallooing, and hunting among the trees. But they don't like the sun: it makes their legs wobble and their heads giddy. They could not find Bilbo with the ring on, slipping in and out of the shadow of the trees, running quick and quiet, and keeping out of the sun; so soon they went back grumbling and cursing to guard the door. Bilbo had escaped.
The Hobbit - Chapter V: Riddles in the Dark
While it clearly states the Goblins didn't like the sun, they were able to overcome their dislike to hunt Bilbo for whatever reason drove them on. This "ability" of the Goblins of the Mountains is reconfirmed in the Lord of the Rings, when the Uruk-hai of Orthanc drive the hobbits through the day and night.
‘Now straight on!’ shouted Uglúk. ‘West and a little north. Follow Lugdush.’
‘But what are we going to do at sunrise?’ said some of the Northerners.
‘Go on running,’ said Uglúk. ‘What do you think? Sit on the grass and wait for the Whiteskins to join the picnic?’
‘But we can’t run in the sunlight.’
‘You’ll run with me behind you,’ said Uglúk. ‘Run! Or you’ll never see your beloved holes again. By the White Hand! What’s the use of sending out mountain-maggots on a trip, only half trained. Run, curse you! Run while night lasts!’
This phenomena seems to be repeated throughout the legendarium with orcs repeatedly fighting, running, moving in sunlight. It appears to be more of a psychological battle for the Orcs, similar to the gloom the darkness of Mordor brings on the people of Gondor before Sauron's attack.
