18 MCU Actors Who Were Also In The Walking Dead

On The Walking Dead: Birdsell portrayed Hannah in the very first set of Walking Dead Webisodes, which followed her character as she tried to protect her children only to get bitten and torn in half by walkers, becoming the iconic Bicycle Girl walker from The Walking Dead's very first episode.

In The MCU: In the first half of the fourth season of Agents of S.H.I.E.L.D., Birdsell turned up as Lucy Bauer, one of the scientists at Momentum Labs who was betrayed by Eli Morrow and put into the Quantum Particle Generator, though she came back as a ghost-esque figure seeking revenge.
