Lindsay Lohan was announced by Variety yesterday as joining the cast of a granny caper comedy to star Shirley MacLaine, Olympia Dukakis, Rosario Dawson, and Channing Tatum. She was even supposed to begin shooting for the film on Thursday. Now MacLaine’s rep says that Lohan is in no way confirmed as signing on to the film, Poor Things, and it looks like her well-publicized DUI may have cost her the role:

According to MacLaine’s rep, there’s actually “no deal” in place for Lohan to act in “Poor Things,” produced by and starring MacLaine. The rep added that casting isn’t set, and shooting wasn’t scheduled to start for a couple weeks.

That’s not what we were hearing just this weekend, when several very reliable sources (and the trades) were saying that Lohan was set to begin shooting on Thursday for three weeks, and Still Rolling Productions — the company producing “Poor Things” — said that Lohan’s DUI arrest wouldn’t affect shooting.

We’re still waiting to hear back from Lohan’s rep, and there’s no word yet from the production company as to Lohan’s (and the production’s) official status.

It’s not surprising that Lohan’s DUI cost her the role, especially if they were going to begin filming this week and didn’t want to hold up production for her. After all, she delayed production on Georgia Rule just by being a brat and now she’s caught up in a DUI. It’s not like they’re going to wait for her. Her last two films weren’t exactly hits a the box office.

Lohan’s hard working rep has issued a statement about Lindsay checking into rehab. Her lawyer was said to have driven here there, and her rep says what they always say about how we should respect her privacy, even though Lohan doesn’t know the meaning of the word:

“Lindsay admitted herself to an intensive medical rehabilitation facility on Memorial Day. Because this is a medical matter, it is our hope that the press will appreciate the seriousness of the situation and respect the privacy of Lindsay as well as the other patients receiving treatment at the facility.”

Splash News has the first pic of Lindsay’s reluctant walk to rehab. She took her last stay in rehab so seriously. She’s surely going to be bucking the staff at Promises, but hopefully they’ll teach her some humility and discipline. Or not.
