Seth MacFarlane has quit Family Guy until an agreement is reached

Seth MacFarlane has decided to quit Family Guy until an agreement between the Writers Guild of America (WGA) and the studios is reached.

The mastermind behind the hit Fox series has walked out on the show to demonstrate his support for the ongoing writers' strike and decided he will quit the show until the WGA receives a new deal.

MacFarlane has left both Family Guy and American Dad after making it clear to 20th Television that neither himself nor the other showrunners - Brian Boyle, Matt Weitzman, Rich Appel and Alec Sulkin - will return as long as the writers remain on strike.

The multiple Emmy-award-winning comedian - who also voices the iconic character of Peter Griffin - has also been spotted out on the picket lines amid the WGA strike, per Deadline, with photos of him surfacing alongside other union members.

MacFarlane's industrial action doesn't come as much of a surprise considering the significant role he played in the previous WGA strike which lasted 100 days between 2007-2008.

While the cartoon genius has already completed all of his duties for Family Guy, which ended its 20-episode 21st season last week on May 7, he still has quite some work left to do on American Dad which started its 20th season back in March.

Deadline reports: "There is quite a bit of runway to go before the wheels come off.

"The animated satire has about three months of scripts, v/o, etc already completed. Then the studio will have to figure out what steps to take next."

The outlet also reports that, unlike other high-profile showrunners and talent, MacFarlane and his Fuzzy Door Productions have 'not received a suspension letter from the Comcast-owned company' for their industrial action.

And the gang behind Family Guy and American Dad aren't the only big names advocating for the writers' strike.

Last Tuesday (9 May), President Joe Biden also expressed his support for the writers, adding that he hopes they are given 'the fair deal they deserve as soon as possible'.

He went on to highlight 'the importance of treating storytellers with the dignity, respect and the value they deserve'.

"This is an iconic, meaningful American industry. And we need the writers and all the workers and everyone involved to tell the stories of our nation and the stories of all of us," Biden added.
