The actress, who won an Academy Award for her performance in 12 Years A Slave, stars in the upcoming blockbuster as Maz Kanata.
But according to the SUN,director JJ Abrams reportedly wasn't impressed by her performance and has been forced to cut several of her scenes down in the final edit.
He was left unconvinced by what he saw and ordered for Lupita's dialogue to be re-recorded.
A source told the paper:
"The CGI seemed to be what Lupita struggled with, perhaps because it meant she felt less of a connection to the character."It’s ultimately quite embarrassing for Lupita but she’s still thrilled to even be in such an iconic movie."
"There was a general sense that something wasn’t working so a lot of her scenes ended up being either re-worked or cut. Unfortunately she just didn’t end up delivering.
"It does happen in Hollywood, but not usually with Academy Award winners. Her part in the final film will now be a lot smaller than was initially expected.
