Responding to a viewer in a Reddit Ask Me Anything thread, the 30-year-old said the historical episode was ‘tough’ to film.
“You know the scene when we’re in the bus? I kept crying. I kept looking back at Vinette [Robinson, who played Rosa Parks in the episode]. I didn’t want Yaz to be crying in that moment that goes on to change history.
“I could not look at Vinette without crying. It just felt so real. The supporting artists were so brilliant and the set was amazing. I just couldn’t stop crying.”
The episode will focus on Yaz, who uses the Tardis to visit her grandmother in India during the volatile time period.
“There’s another episode which is historical, which I’m really excited about,” Gill said during the Reddit Q&A. “I am genuinely excited on a Sunday, what I’m tweeting is real. I can’t wait to see what it looks like.”
“The most memorable thing that happened behind the scenes was when Bradley threw himself down eight wooden steps. He properly set it up and he often trips up to entertain us. He really tries to make us laugh.
“He’s really good at it, and he rolled down eight wooden steps and then he laid at the bottom of the steps and said ‘Anybody want a cup of tea?’”
