It is the same principle that made NBC cast James Spader in The Blacklist, a show which currently stands as the biggest new series of the 2013-14 US television season, and the highest rating scripted series on NBC. Yes, the same NBC that has endured a massive failure with The Michael J Fox Show.
So, the question is, do shows really need big stars to succeed?
It's hard to prove it one way or the other. The Blacklist is a hit, while The Michael J Fox Show is a flop. The Walking Dead has no recognisable, big name stars - at least, nobody on the level of Fox or Spader - yet it's the most successful drama on the planet. Parks & Recreation has some fairly recognisable stars, yet draws low ratings.
Even the most talked about shows are a mixed bag. Game Of Thrones built itself into a massive success with a relatively unknown cast - then proceeded to kill off the most recognisable faces (Sean Bean, Mark Addy, Jason Momoa) over the back half of its first season. Meanwhile, Kevin Spacey (and to a lesser extent, David Fincher) is as big a part of House Of Cards' success as anything on the creative side of the show.
It seems clear that television shows don't need big stars to succeed in the ratings - though the right star in the right role, like the charismatic Spader leading the cast of The Blacklist, can probably bump up the figures a little. Big names make life easier for marketing people, too; it's a slam dunk to attach promotions for a show to a recognisable star.
But what about viewer enjoyment at home - is our enjoyment of a show increased by the presence of big names?
For example, would we enjoy Boardwalk Empire as much if Steve Buscemi wasn't leading the cast? Would we have seen straight through The Newsroom - heck, would it even have made it to air - if not for Jeff Daniels and Aaron Sorkin? Would I have been as engrossed in True Detective if anyone other than Matthew McConaughey was in the lead role?
I'd like to think I'm not swayed by celebrity cast members. If I'm being completely honest, I tend to imagine I have a discerning taste in television and can see through gimmicks like this. And it's true, I like plenty of shows that don't boast a big name cast - my favourite shows right now, The Walking Dead and Hannibal, both feature relatively fresh faces.
Yet, I do tend to geek out about big name stars. Buscemi is the primary reason I started watching Boardwalk Empire (though my love of the show doesn't include him now), and I forgave plenty of The Newsroom's first season because "it's Sorkin". I think Spader is the best member of The Blacklist's cast, to the point that the show drags when he isn't on-screen.
Maybe shows don't need big names to be enjoyable. But I feel like they do help build some excitement.
