Grassfire Nation, a conservative activist group, published the contact information to five of Hollywood's top directors, producers and stars in an email blast to its supporters on on Friday.
The email — which was also posted on the Grassfire Nation website — was subject lined: "Stop the Obama team 'death ad' funded by leftist elites."
According to the email, Bill Maher, Steven Spielberg, J.J. Abrams, Jeffery Katzenberg and Morgan Freeman are "guilty by association" to a controversial new ad put out by Priorities USA, a Pro-Obama superPAC.
The email claims that the stars support for the super PAC — Maher and Freeman have both given $1 million, while Katzenberg has chipped in $2 million — makes them legitimate targets to harass because they have not "disowned" the ad.
"We've included the names and contact numbers below," the group writes. "Demand they use their influence to get this ad pulled with apologies!"
After asking its supporters to sign a petition, the conservative group listed phone numbers for each of the celebrities, nine numbers in total.
The numbers connect callers to the talent and management agencies that represent the men.
"We've gotten three four calls into the switch board," one Hollywood exec told BuzzFeed on Friday afternoon. "I'm sure there will be more. The only thing our receptionist said is that they all seem to be reading off a script."
