As it gears up for its fifth and final season, spy caper 'Chuck' keeps adding to its impressive guest star roster.

Hot on the heels of signing 'Star Wars' legend Luke Skywalker Mark Hamill to appear as a baddie, it's been announced that Craig Kilborn will also be guest-starring as a villain.

According to TVLine, Kilborn will be feeling the force alongside Hamill in the Season 5 premiere.

He'll play Roger Bale, a charming yet conniving investor who's stolen money from some of the world's most dangerous people. Oh, and it turns out that Roger's rather dangerous himself.

'Live from New York: An Uncensored History of Saturday Night Live' was an oral history of the late night staple, and turned out to be very compelling reading.

More surprising was that James Miller and Tom Shales' follow-up book about ESPN was just as riveting, and even led to a movie deal. So Keith Olbermann and Dan Patrick decided to cast it on 'Countdown' (Weeknights, 8PM ET on Current TV).

'Those Guys Have All the Fun: Inside the World of ESPN' went just as deep into the inner workings of the little cable network that could, and because it's players aren't big celebrities, it makes sense that this one was optioned for film over 'Live from New York.'

Comedy talk shows are a vastly underrated wasteland of quality programming, but they're shorter on female eye-candy than the floor of the Consumer Electronics Show.

ABC is hoping to change that by giving comic babe and former Talk Soup slinger Aisha Tyler her own piece of programming.

The network is letting her develop a pilot for a "hybrid" style talk show that incorporates sketch, stand-up and other variety comedy into a fully "wired" show that will communicate with their audience over the Internet's series of complex tubes.

It's hard to see beloved characters leave your favorite shows. You have created a bond with them, perhaps even projected their values onto yourself in an effort to raise the self esteem you had before, say, you fell down the Law & Order rabbit hole and started to believe the shows were actual news and not just "ripped from the headlines." But change is inevitable, and sometimes, it works out. Here are a few that worked (at least for me).

1. Current cast of Law & Order: I know, I know, who could replace Lenny Briscoe? No one, really. But the current pairing of Anthony Anderson and Jeremy Sisto as NYPD partners is the best the series has produced. They changed the feel of the show. Perhaps because we're still getting to know them, they are less predictable then previous tandems, and both evoke a certain hard-nosed quality that seems a bit more gritty and real. Plus, Anderson has chops as a stand-up comic, and could easily fill the wisecracker role, if need be.
