Another one to add to the list of numerous villains that The Arrow will have to deal with. Yay!
Chin Han (The Dark Knight, Contagion) will be joining the cast of the CW’s Arrow (can we just call it Arrow now, without the CW part?). The actor will play Frank Chen, an old friend of the Queen family whom has become a wildly successful businessman.
Chen will apparently play a villain for the CW’s most popular series, as he has ties to The Undertaking, the mysterious group led by Malcolm Merlyn [John Barrowman].

Han is a great actor, and I think he’ll definitely benefit Arrow by being part of the cast. I work at DISH with plenty of other Arrow fans who will recognize him from The Dark Knight, and should agree with me. Wednesday night offers me a lot of great shows, so I’ll catch Arrow and a coulee more live, but then record the rest to my DISH Hopper. I can record up to 6 programs at once during prime time hours, so I don’t have to worry about my overlapping shows like I did with my old DVR.
