Director Phil Coulson is going to battle Agent Peggy Carter in a most unusual arena.
Gregg and Atwell already have a musical rivalry going, having battled it out in a Dubsmash War. Of course, both were then able to recruit help from their respective allies – Team S.H.I.E.L.D. and Team Carter. The Lip Sync Battle will be a one-on-one affair.
Atwell just wrapped up Agent Carter’s second season on ABC, and rumor has it that the series will return for a third.
Gregg returns to TV when Marvel's Agents of S.H.I.E.L.D. enters the back half of its third season on March 8. The show has already been renewed for a fourth season.
Marvel's Agents of S.H.I.E.L.D. airs Tuesdays at 9 p.m. ET on ABC.
