Williams' character on the beloved TV series, bad girl Jen Lindley, was killed off but she insists she's still open to returning to the drama for a TV movie.
She tells Los Angeles radio DJ Ryan Seacrest, "In a heartbeat I would go back, but I would have to go back as a ghost."
And Weinstein, her producer for new film My Week With Marilyn, insists he'd like to be involved: "I will produce it... It's gonna be a period piece."
Dawson's Creek also featured Katie Holmes, James Van Der Beek and Joshua Jackson.
