Lindsay Lohan -- Lifetime Producers Worried Sick -- THEY DON'T GET IT!

Sources close to Lindsay Lohan's Lifetime movie tell TMZ ... producers have been in hysterics these past few weeks over LiLo's latest hijinks, and we're left to wonder ... WHY?!?!?!

According to our sources, producers were particularly upset over her car accident on PCH. We're told the producers have five big concerns:

-- The company that insures the movie might bail
-- Her probation could be violated for lying to the cops
-- She could be prosecuted for lying to police
-- She could crash her car again
-- She's going to clubs where bad things happen

But here's the thing ... when has a Lifetime movie ever gotten this much press (besides the one where Jennifer Love Hewitt played a hooker)? And don't they know ... nothing bad ever REALLY happens to Lindsay.
