Stephen Amell is excited about two things: the finale for "Arrow" season 3, and he's about to film scenes as Casey Jones for "Teenage Mutant Ninja Turles 2."

The actor posted on Twitter, "7 days left with Oliver Queen. 17 days until I'm Casey Jones."

The comments, however, are more about "Arrow" as they are about the "Teenage Mutant Ninja Turtles 2."

One of Stephen Amell's fans said, "do you mean 7 days until oliver and felicity have sex."

Another commented, "im sad season 3 is ending but im soo happy you're doing a movie."

One person couldn't contain his excitement, "WAIT SO YOURE FILMING THE FINALE THAT MEANS YOU KNOW WHATS HAPPENING IN THE FINALE OH MY GOD."

Stephen Amell talked about taking on Casey Jones in "Teenage Mutant Ninja Turtle 2" and how it feels to play another vigilante after his Oliver Queen character in "Arrow."

"I'm just glad I get to play a vigilante on the big screen," he quipped when asked by Comic Book.

"Obviously, the similarities are right there on the surface, he's a vigilante. But, if the audition process and the script are any indication the character is going to be fundamentally different," he said.

"As a matter of fact, it is almost like the character of Casey Jones - at least in this iteration of Ninja Turtles - is almost like the Oliver Queen people know from the older comic books."

Stephen Amell also said that playing Casey Jones in "Teenage Mutant Ninja Turtle 2" is a nice departure from his "Arrow" routine.

"As much as I enjoy playing Oliver Queen it is very important to me to stretch out a little bit and believe me, I know I'm playing another vigilante. I know this! You're going to have to trust me when I say that not only is Casey Jones different from Oliver Queen, but filming a big feature film is really different than filming a television show," he said.
