Dear Jeremiah Executives and Producers: 

We want Sean Astin!

[Personalization is important!]

As a fan of Sean Astin and his show Jeremiah, I urge you to air the episodes 
remaining in the second season in January 2004. If you decide to produce new 
episodes for a third season, you will have a loyal viewer tuning in every week.
I will look to the decision to keep Jeremiah on the air as a reflection of 
your desire to support the vocal community of Showtime subscribers and Sean 
Astin fans.

I discover something new with every viewing so I enjoy watching the reruns as 
well. I am sure it is helpful for the new viewers and subscribers just now
tuning in. 

I appreciate you taking the time to read my letter and producing this quality
show so far.

Thank you,
[Your Name]
