Beetz plays role of Domino in the upcoming R-rated sequel with Reynolds as the superhero.
"Honestly, it's amazing kind of watching Ryan do his thing because you think like, 'Oh, he has the mask on and you can ADR all of it' or whatever, but he is genuinely incredibly talented, and it's pretty impressive to watch.
"He's just really good. And so, for me, this is the biggest thing I've done, so I've been very much sort of observing and it's been a good vibe set to observe on and (there are) a lot of really talented people," Beetz told Entertainment Tonight.
