Value of Actors Expo to writer

[J off course]

I just found out tonight that the arts center where I work, will be
host to an actors expo involving workshops with a TV actor,
a famous director and a successful producer who has a movie
out now.

I read a few lines of their promotional material and it said that the information shared in the expo could also benefit writers.

Any writers out there that has attended one of these things and
thought they came away with something valuable pertaining to
their writing and writing career?

If I can corner the producer, is it ok for me to pitch an idea or will
I be fighting off actors with their headshots? <smile>
