Rented this a few times in mid to late 90's
This is not a dr suess book story, it is real people. The main female is a larger dark haired lady who was in a lot of comedy type movies at the time. I can't remember exactly what the connection to dr suess is in this anymore. It was a good movie and while I and all 4 of my kids remember it none of us have a clue about the title. I've searched every way I can think of. Any ideas?
It is not Grinch, 10 000 Fingers of Dr T. or Cat in the Hat

I asked and then actually after 5 years of trying found the answer myself!

For anyone who is a dr seuss fan this is an excellent movie!

In Search of Dr Seuss - 1994

Staring Kathy Najimy as a reporter researching dr seuss's life. Real people play some of his book characters that she interviews, including Billy Crystal. There are bits of his stories through out the movie.

I loved this movie as much as my kids did, now I can go try and find a copy of it
