The news that 'Mad Men' star Elisabeth Moss has signed on to star in upcoming new drama 'Top of the Lake' has led Australia's national broadcaster, the ABC network, to pull out of the project.

It had reportedly pledged around $600,000 to the miniseries on the assumption that the lead character, an Australian police officer, would be played by an Australian actress.

An ABC spokesman told the 'Herald Sun': "We went into this with the understanding the lead actor would be an Australian. But when that could not happen, we removed ourselves from the deal."

The spokesman added, "We love Elisabeth Moss, but she's not an Australian. We have a fine calibre of Australian actors available and we would have preferred to see one of them in the role."

We're still not sure when NBC's '30 Rock' will return to our screens (fingers crossed for early midseason), but when it comes back, expect an extra injection of hilarity from Mary Steenburgen.

According to EW, Steenburgen will guest-star as Charlotte, the "highly spirited and attractive" mother of Elizabeth Banks' character, Avery.

In her multi-episode arc, expect to see WASP-ish Charlotte going head to head with Jack (Alec Baldwin).
