No offense to your friend, but she's not exactly the body type one sees on the runways at the major fashion shows in Milan, Paris, New York, and London.Yeah... I just don't see Wonder Woman coming from her.
Lots of people said the same thing about Christopher Reeve and Superman. And Heath Ledger and the Joker. And countless others.
In Bale's case, he lost a ton of weight for that role, so, losing the weight was probably tougher than putting it back on. A closer analogy would probably be Chris Hemsworth putting on the bulk for Thor
Again, though -- Gadot is a model. Models in this day and age are required to reduce their weight to an absurd, unhealthy degree and keep it down at all costs. So it's actually a pretty perfect analogy.
My friend Yasmine Petty is also a model. Funny how she does not have to do this.
