"Remembrance of the Daleks" was also the first story in which Aldred's Ace was a regular companion, having joined at the end of "Dragonfire". Cartmel worked with Aldred to make Ace different than most companions: less of a "screamer" and more tomboyish. Aldred recalled the taking on the Daleks made her feel like a "real assistant". Aldred did many of her own stunts, bonding with the new stunt coordinator, Tip Tipping. She found the experience "terrifying" at first. Aldred has said that she is proud of the scene where Ace beats up a Dalek with a baseball bat, calling it one of the best things she has done in her life. Aldred was also trained in firing guns for the scene where she shoots a Dalek.
