Congratulations - You're Forever Izzie!

Being on a popular and successful television show is one of the aims of every working actor out there. Nobody wants to be that person who always has a new pilot in the works and might be getting a deal on ABC for a mid-season replacement show.

Of course, there is a downside too.

Why don't you give Jason Alexander a call about it? Maybe the entire cast of Friends could tell you a thing or two?

And now, you can add Katherine Heigl to that list.

From now until the end of time, every appearance of Katherine Heigl in a major motion picture will be the equivalent of Dr. Isobel "Izzie" Stevens playing the role of the smart, blonde female lead.

Case in point, The Ugly Truth.

For the record, avoid it like the plague. Bad doesn't seem like a strong enough word.

Anyway, despite only watching Heigl and Gerard Butler go back and forth on film two nights ago, I can't tell you the name of Heigl's character.

Why? Because regardless of whatever her name was, she was Izzie, playing the part of a character in a very mediocre movie.

Now, this has happened to countless people in the past, including the poor souls mentioned off the top. I mean, Matt LeBlanc has officially fallen off the face of the Earth because he will forever be Joey Tribiani, and nothing he does will ever change that.

For Heigl, it's going to take a dramatic departure from every role she's ever played for people to not see Izzie Stevens starring in another craptacular romantic comedy coming soon to a theatre near you.

I say blood-thirsty serial killer with short dark hair and all goth'ed up on Criminal Minds...
