Sydney Sweeney is giving Tom Cruise a run for his money. 😮 The actress posted a video on Instagram of her standing on top of an in-flight biplane performing a wing-walking stunt à la Ethan Hunt. Sweeney balances on the plane, doing her version of a stunt Cruise perfected for 'Mission: Impossible — The Final Reckoning,' while holding a camera to capture the exciting ride. 📷: Sydney Sweeney/Instagram; Paramount 🎥: sydney_sweeney #SydneySweeney #TomCruise #MissionImpossible
