Let's talk about boob size.
Wonder Woman's, specifically.
It might seem a trivial or inappropriate topic, but actually, it is very important.
Generally speaking, I couldn't care less about the size of a woman's boobs. Big, small, medium - doesn't matter.
But when it comes to iconic comic book superheroine Wonder Woman, I feel rather strongly that size does matter, which is why I'm completely flummoxed over the recent casting of Gal Gadot as the Amazonian princess in director Zack Snyder's new 2015 Man Of Steel sequel.
The movie, tentatively titled Batman vs Superman, will see Wonder Woman appear opposite Ben Affleck's Batman and Henry Cavill's Superman.
Snyder said in a statement: "Wonder Woman is arguably one of the most powerful female characters of all time and a fan favourite in the DC Universe.
"Not only is Gal an amazing actress, but she also has that magical quality that makes her perfect for the role."
We're still unsure what that "magical quality" is. The 28-year-old Israeli former model and beauty queen is a stunningly beautiful girl, but she has the body of a typical model, which is to say the body of a 12-year-old boy.
You probably don't recognise Gadot because her only notable role to date has been in the Fast & Furious flicks.
She appeared in the last three instalments as a supporting character named Gisele, a sexy exotic who is part of Vin Diesel's crew.
Glaring lack of any substantial acting experience aside, watching her in those films, I never dreamed I was looking at the next Wonder Woman - because she has no boobs.
