Jodie Whittaker pretended to forget her lines during Mandip Gill\'s \'Doctor Who\' audition.
The 37-year-old star - who had been cast as the titular Time Lord by this point - wanted to make the actress feel more comfortable as she was trying out for a role in the BBC sci-fi series, to help get rid of any nerves.
Speaking to Radio Times magazine, Mandip said: "I didn\'t think it came across like that... [laughs] The great thing was, you didn\'t know your lines!"
Jodie admitted: "I did that on purpose."
Mandip, 32, didn\'t realise her co-star was helping her out during the audition, but said it had the desired effect.
She added: "Really? Thanks, because it made me feel at ease."
Jodie explained: "It\'s so intimidating when the other actor knows all their lines, but there\'s meant to be room for playing and having fun.
"I knew you\'d be more comfortable if I wasn\'t overly prepared."
Tosin Cole - who plays Ryan alongside Mandip\'s Yaz and Bradley Walsh\'s Graham - revealed his first impressions of his co-stars, and he joked \'The Chase\' host is "the most unstable" when it comes to his moods during filming.
He said: "Jodie\'s the most consistent because she\'s always quite high-energy, isn\'t she?
"Showbiz [Tosin\'s nickname for Bradley] is up and down - one minute he\'s grumpy, one minute he\'s pranking, or he\'s grumpy and he\'s pranking. You never know with Brad - he\'s the most unstable."
Showrunner Chris Chibnall recently hinted the next series - which will feature Jodie as the Doctor - will be back in 2021.
He teased: "We have very big, ambitious plans for our third series together ... it will be next year sometime, hopefully, unless my holiday goes on for a really long time, which is always tempting."
