Did Rachel Griffiths announce Brothers & Sisters is axed?

Last night surprise Logie presenter Rachel Griffiths appeared to indicate US drama Brothers and Sisters is about to be axed.

During a chat with host Shane Bourne, she was asked about her plans to direct her first feature length movie in Australia next year, called B-Model.

“I’m soon to be unemployed so I checked in with Centrelink and I don’t know if anybody’s noticed they’re cracking down on the whole welfare thing. So I went to see Centrelink and said, ‘Looks like I’m out of a job and wanna sign up.’

“And they said, ‘You have to be looking for work.’ So I said I’m trying to direct a movie, and it’s all gone crazy.”

When joking about her attempts to find work she added, “I looked them in the eye and said, ‘I think I am going to be unemployed,’ and they didn’t seem to be very warm.”

ABC drama Brothers and Sisters is yet to be renewed for the US Fall season and is one of the shows tipped to go under the axe.

It's unlikely having a new season.
