Breckin Meyer's 'Franklin & Bash' co-star Mark-Paul Gosselaar has a big head ... literally. When James Van Der Beek appeared as a guest star on the show, there was barely room on the screen for the diminutive Meyer amidst the vast quantities of noggin. Meyer described the experience Wednesday on 'Access Hollywood Live' (weekdays, syndicated on NBC), appearing together with Gosselaar, who was co-hosting.

Billy Bush set up a clip of a scene that included Meyer, Gosselaar, and Van Der Beek. "The two giant-headed people," said Meyer. "It's awesome. Check it out. It's like watching Easter Island. Check it out." After the clip, Meyer said he had to give his two scene partners nametags to tell them apart. Finding light to stand in was also a challenge. "I'm just saying, it's like Mardi Gras with them," he said. "It's insane."

James Van Der Beek has landed a recurring role on NBC's 'Mercy.' The 'Dawsons Creek' alum will play Dr. West on the freshman medical drama series, a "cocky" and "womanizing" doctor who is also harboring a major secret. If all goes well, Van Der Beek -- who has recently guested on shows like 'Ugly Betty,' 'The Forgotten' and 'One Tree Hill' -- could become a series regular. In the meantime, no word on when he'll officially scrub in. [Ausiello Files]

More casting news after the jump.

Have you been missing those references to Scherbatsky's Canadian life? If you know what I'm talking about then you'll be overjoyed to know that on April 21, How I Met Your Mother will be all about Robin Sparkles, Robin Scherbatsky's alter-ego teen singing star. The entire episode is planned as a flashback to the 1980s 1990's when Robin became a one-hit wonder with the song "Let's Go to the Mall." Well, it turns out that wasn't her only song. Carter Bays and Craig Thomas, How I Met Your Mother's co-creators, composed a ballad. "Sandcastles in the Sand" was the flip-side of "Let's Go to the Mall." It's supposedly in the style of a power break-up ballad, like "Foolish Beat" and "Toy Soldiers."

This week we have: 30 Rock, Desperate Housewives, Greek, Grey's Anatomy, Heroes, How I Met Your Mother , Numb3rs, Smallville and Ugly Betty. (SPOILERS FOLLOW!)

One thing I didn't enjoy much about NBC's comedy Will & Grace was the constant famous guest stars popping in almost on a weekly basis. At times, it felt like the episodes were written for those guest stars instead of writing the episodes first and then trying to find a famous person to fill in a role. Since the strike ended, I fear that How I Met Your Mother is heading towards that same path. Don't get me wrong, I love seeing guest stars here and there in a series but having them pop up week after week can get tiring. So I hope this is only a renewal stunt for the series and not something that will become the standard.

Unless you have been living under a rock, you know that Britney Spears guest starred in the March 24 episode of HIMYM. Alicia Silverstone was set to appear in a few episodes (some suspect her character would have turned out to be the mother) but bowed out when Spears was hired because Silverstone was worried that her performance would be over-shadowed by Britney's appearance.

The latest addition to the HIMYM guest star list: Dawson's Creek's James Van Der Beek! Slight spoilers about the role and episode ahead!

(S02E04) I felt like I was watching a bizarro version of Ugly Betty this week. Betty was a cheater, Justin belched, and the guy from Dawson's Creek was an insensitive jerk! What's next--Hilda dressing conservatively? There were several unpleasant surprises in this episode, but Gio's absence probably made some of the viewers happy. It's always difficult to watch the episodes where obstacles are set up for each character, but how else can there be a happy ending later on? Still, it took a while to get over the shock of seeing Justin wearing his Dad's leather jacket and hearing him say things like "Whatevs."

The numbers are in and Super Bowl XLI was huge. Coming in at 93.1 million viewers, it was the third most watched program in history, and the second most watched Super Bowl. Having the lead-in to end all lead-ins also helped Criminal Minds put up the best numbers ever for the series. The special episode following the game averaged 26.2 million viewers.

Is that a disappointment? Last year, the post Super Bowl episode of Grey's Anatomy drew a considerably larger 38.1 million viewers. We can chalk part of that difference up to the fact that Grey's was more of a hit show going in, but I think more of it has to do with the subject matter.

Criminal Minds is never a touchy-feely, happy bunnies on clouds kind of show, but the post Super Bowl episode was dark even by their standards. Come on, Dawson chaining up a woman and setting the dogs loose on her? That's asking a lot from the family friendly Super Bowl audience.

It looks like 2006 will be the year of the Dawson's Creek kids after all. We've already been hearing plenty about Katie Holmes and MIchelle Williams, and, as I was happy to report earlier this month, Joshua Jackson is starring in a legal drama on CBS (hopefully) next fall. Now comes word that James Van Der Beek (aka Dawson) will also be returning to series television, also on CBS. Van Der Beek has been cast in a comedy pilot, Sex, Power, Love & Politics, a comedy that, like Van Der Beek, has too many names in the title. It's about Capitol Hill staffers in their 30s, and that's about all we know. I'm not sure what role he has, but he'll be acting alongside Ally McBeal alum, Jane Krakowski, a role Adam reported on earlier this month.
