During an interview with The A.V. Club, Vik Sahay said that he first auditioned for the role of Morgan, and when the auditions came down to just him and Joshua Gomez, and Gomez got it, the producers instead offered Sahay the then-smaller role of Lester. Lester since became a more prominent character than he was in the pilot.
At the close of the second season, declining ratings and stiff competition from the other networks had indicated that "Chuck" would be canceled. However, due to petitioning from its loyal fan base specifically aimed at one of its sponsors (Subway), the show was renewed for a third season, in an unprecedented partnership between NBC and the sandwich chain, helping to cover the production costs. "Chuck" continued to face cancellation for its subsequent seasons, with its fifth season becoming its final one, beginning October 28, 2011, and ending on January 27, 2012, with a two hour finale.
Throughout the series, Chuck almost always wears classic black Converse Chuck Taylors, often referred to as "Chucks."
