The Teenage Mutant Ninja Turtles sequel, which incidentally is called Half Shell, has slowly been gaining steam with its production.

Already, they've cast a number of people as well as returning Megan Fox, Will Arnett and William Fichtner to the screen in their respective roles as well.

One feature that the first one lacked was any noticeable or memorable characters from the original cartoon series that many of us are more familiar with.

For example, Casey Jones - that nutjob with the hockey mask - was noticeably absent, whilst the henchmen duo that was Bebop and Rocksteady were also missing.

Luckily, that's not the case as just a few hours ago, the role of Rocksteady was cast by none other than our own Sheamus from WWE.

Yes, the red-haired former WWE champion will be playing Rocksteady - that's the rhinoceros one - whilst Gary Anthony Williams will be playing Bebop.

Obviously, since Sheamus is currently playing a heel in his wrestling career - that's shorthand for playing a bad guy - this fits into his current persona.

While the first one had problems with tone and so forth, the sequel looks like it's correcting the mistakes from the first one.

What do you think? Yay or nay? Let us know in the comments!
