The son of Greg Grunberg, Jake, is just as heroic as the characters his dad stars with. Jake was diagnosed at a very young age with epilepsy.

Grunberg is very involved to help fight epilepsy and raise awareness. Earlier this year, Grunberg recruited his fellow Heroes in an online auction to benefit the cause. The auction raised thousands of dollars.

Grunberg is also scheduled to participate in the National Walk for Epilepsy in March 2007. Click here for more information on that.

Sam Loeb was an amazing young man who was taken away from us way too early.

Sam was the son of prolific writer Jeph Loeb, who you may know from his comic book work, but may also know from his work as a writer and producer on such shows as Smallville, Lost... and Heroes. He passed away at the age of 17 in 2005.

In the past, some of Loeb's contacts such as Smallville's Erica Durance and artists like Tim Sale, Jim Lee, Michael Turner, Rob Liefeld and others, have all done their part to help raise money for an annual scholarship in Sam's name. The scholarship goes to the student who "best exemplifies Sam's qualities both as a student and as a person - in other words, brilliant with a sense of humor," according to an article on Newsarama.com.

When we interviewed guest actor Christopher Eccleston he told us about several of the charitable organizations that he has given time toward.

For starters, Eccleston is a patron of an extraordinary theatre company called Celebrity Pig, which is made up of people with a learning disability. He has been involved in a couple of their productions, and hopes to do more.

In addition, Eccleston is an ambassador with the learning disability charity MENCAP, and has traveled to the tsunami site Banda Aceh for the Red Cross.

Noah Gray-Cabey (Micah) has his own foundation which benefits both inner-city children and people suffering from AIDS in other countries.

More information will be posted as it becomes available.
