The helmer was effusive about Cumberbatch's performance in the sequel, revealing that he wanted to cast him immediately after watching his performance in Sherlock.
"One day, Damon Lindelof texted me and said, 'You should check out Sherlock'. And I watched Sherlock, and was completely blown away, there was this absolute undeniable feeling about it.
"Certainly it was important to hear the words come out of this actor's mouth, and so we got Benedict the pages and he sent an iPhone-taped audition to us, but it was almost a little bit of a formality."
Abrams went on to suggest that Cumberbatch's presence had raised the standard of performances across the board.
"Being on the set with him... I think everyone was bringing their absolute A-game. I think, frankly, in a way, [his] presence sort of elevated everything," he added.
"Time and again, every scene, Benedict brought a surprising, unexpected, grounded, real and often terrifying aspect to the role. So we are incredibly grateful, all of us."
