Lost and Smallville Alumns Guest Star on CHUCK August 10, 2011 Chuck, News As recently reported by TV Line, CHUCK has landed some very interesting guest stars for an upcoming episode in the show’s final season on NBC. Actors Justin Hartley – who played Oliver Queen aka Green Arrow – on the long-running WB/CW series Smallville and actor Jeff Fahey – most recently from the ABC juggernaut series Lost – will guest star in the second episode of Chuck, playing – get this – brothers! Fahey will play Karl Sneijder, the CEO of a diamond company called Natal Jewelers with mines in South Africa. He has been under investigation by the CIA in the past for alleged criminal activity, but no charges have ever been able to stick. Hartley will play Wesley Sneijder, the handsome younger brother of Karl. He is a Dartmouth and Oxford-education anthropologist, who has done everything he can to stay out of his brother’s business. Well, as you can guess it, Karl’s enemies kidnap Wesley, which brings Karl to the doorsteps of the newly formed Carmichael Industries – the company that Sarah and Chuck Bartowski (Zachary Levi and Yvonne Strahovski) started with the money they received from Alexei Volkoff (Timothy Dalton) on their wedding day – to help retrieve Wesley. Chuck will be back on NBC for its fifth and final season starting on its new night of Friday on October 21. Mark your calendars!
