Jesse Eisenberg discusses how he felt his role as Lex Luthor in 'Batman v Superman' negatively impacted his career while appearing on 'Armchair Expert.
I mean, it was a bad movie and an odd choice for casting, but these things are not his fault.
On that note, I think Jesse is a good actor, but... he's not a Lex. Why do we seem to be trying to cast young skinny dudes as Lex and directing them to play him as a rich spoiled manchild? One of the very few things that have me concerned with Superman 2025 is the casting of Nicholus Hoult. Again, a good actor, but I'm worried about his physicality and his ability to be menacing/physically intimidating.
The newest Lex Luther in Superman & Lois, did a great job. That worked. The writing for his character had some questionable choices. They made him very fragile and pety. Wasn't so much a fan of that. But the actor nailed it.
