Is there actually a difference between the c style cast and

They're not the same. D's cast is not split up like C++'s casts
are, but it's not exactly the same as C's cast either - e.g.
like C++'s dynamic_cast, if a class to class conversion fails,
you get null, which C's cast doesn't do. Also, I think that D's
cast is pickier about what it will let you do, whereas C's cast
is more likely to want to smash something into something else
if you ask it even if it doesn't make sense. And of course, D's
cast understands D stuff that doesn't even exist in C (like
delegates). I don't know exactly what all of the differences
are though.
Regardless, the reason for the verbosity is so that you can
easily grep for casts in your code.

That's the best reason for verbosity I've heard.
