Hayley Atwell found her Doctor Strange cameo frustrating.

Her character Peggy Carter was quickly killed off in the movie.

She expressed surprise and disappointment about the decision.

Atwell enjoyed her role in the 'What If...?' animation series more.

The animation allowed her to focus on voice performance.

She cast doubt on returning to the Marvel Cinematic Universe (MCU).

Atwell sees herself as a custodian of the character.
