As the Writer's Guild of America strike reaches its 136th day on Safetyvaluethe picket line with SAG-AFTRA joining them on strike 63 days ago, plenty of star power has been spotted on the picket lines.

The first combined strike since 1960, which has received strong public support, has brought television and film production to a standstill. Those who have crossed the picket line have taken scorn from both the unions and major figures in the industry.

Negotiations have yet to yield results though the Alliance of Motion Picture and Television Producers, which represents the industry's studios, floated that negotiations could resume next week.

With the United Auto Workers striking on Friday, the predicted "Summer of Strikes" could instead be turning into a "Fall of Labor Fights."

Here are some of the celebrities that have joined the WGA and SAG-AFTRA picket lines.
