Doctor Who: 10 Actors Who Should Replace Peter Capaldi
2. Hayley Atwell
Why She'd Be Great
Atwell is an extremely talented actress, and has consistently proved over her years in the MCU just what she can do. Whether it's been a supporting part in the movies, or leading her own (sadly cancelled) series Agent Carter, she's been funny, smart, silly, and a complete badass.
At the same time, she's also shown great dramatic range, such as her haunting performance in Black Mirror episode Be Right Back. A proven TV lead, nerd credentials, plenty of range and personality, it's hard to think of anyone better suited (indeed, there's only one person). Heck, just the potential of her having a verbal battle with Michelle Gomez' Missy should be enough to land her the role.
Chances Of It Happening
Potentially quite good. With Agent Carter cancelled, Atwell is now mostly out of the MCU, save for potential cameo appearances and a voice role in the animated series Avengers: Secret Wars. Furthermore, her latest TV show - which landed on ABC after Carter was cancelled - hasn't been picked up for further episodes. So, she's available.
Furthermore, she has said - albeit only via a Twitter Q&A - that she wants the role. If she was being truly serious, now is the time to give it to her.
