This reminded me of my favorite anecdote about Homelander's suit. From Jensen Ackles when he showed up on set completely jacked like a superhero:

I was told to beef up, and so I worked out like a madman. The physical preparation was something that I’ve never done before. But I think it helped me get there mentally. I get to set and Anthony’s like, ‘Why didn’t you just tell him to add muscles to the suit, bro?’ And it just deflated me. Just crushed me. All that effort and it was for really nothing,” shared Ackles while speaking with EW.
