Echo Kellum is ready to make "Arrow" terrific. Speaking to MovieFone, he offered a few vague details about Season 5, revealed how badly he wants Curtis Holt to suit up as Mr. Terrific, discussed his interest in appearing on "DC's Legends of Tomorrow" and more.

As to Season 5, he said, "I can't really say too much, outside of that it will be 'terrific!' That it'll be a lot of cool things happening, and just buckle up and get ready for an awesome ride. They're really going for it this season, and I think they're going to bring a lot of cool elements that made the series so great. It's just going to be such a cool cast to work with, with all the new additions this season. I think it's going to be the best."

Asked if he'd like to wear a costume, he shared, "Yes, yes. Second that! Where is my costume? [Marc] Guggenheim, if you're listening, or reading, whatever: Where's my costume? No, I definitely want to suit up really bad. But I understand. It's this arc. You've got to build up to it. But I definitely hope -- and I believe, hopefully, within this season we should see Curtis Holt get there in some capacity. So I'm really looking forward to all that's happening."

"I'd definitely get on 'Legends of Tomorrow,'" he added. "I'd be thankful to be on any of these shows, to be honest, because they're so well done and I'm a big nerd. So for me, it's just like a dream come true to even be a part of 'Arrow,' or any of it. To have a potential to be on the crossovers is, like, 'Wow!' It's mind-boggling."

Starring Stephen Amell, Emily Bett Rickards and David Ramsey, "Arrow" will return to The CW on Wednesday, October 5 at 8 pm EST.
