Arrow: Amell Shares BTS Video of His Last Scene Ever with Gustin's Flash

As principal photography on the epic Arrowverse crossover "Crisis on Infinite Earths" comes to a close, Stephen Amell has shared a behind-the-scenes look at his last scene with longtime costar Grant Gustin.

The actor is seen accidentally dozing off on the set in full costume before being awakened by Gustin's arrival. Amell noted that he learned much from his costar over their many years working together, both as an actor and through his character.

Gustin guest-starred in Season 2 of Arrow before receiving his own Arrowverse spinoff in 2014. Since then, the two characters have worked together frequently across the DCTV shared universe.

Arrow will conclude its eight-season run shortly after the coming "Crisis," closing out the inaugural Arrowverse television series with the end of Oliver Queen.
