After thugs peed on his beloved rug, an affable loser, through a case of mistaken identity gets caught up in a kidnapping case, which he must solve.“`

Agreed with the comments above, I think it's safe to say that their cult following will retain the studio's interest in their work for years to come.

I would ad in an element to raise the stakes by mentioning the German Anarchists who threaten his life.
I.e:
After thugs urinate on his beloved rug in a case of mistaken identity, an affable stoner gets embroiled in a kidnapping caper he must solve to prevent the murderous kidnapper coming after him.

"if the script for the Big L had been written by an outsider with no credentials, no representation, no track record, would it have gotten a reading no matter how well-crafted the logline?"

Good question, DPG. One we can?ask about pretty much every Coen Brothers movie...

All their movies are exceptionally well executed, though.

My take, 3 words longer:

After thugs urinate on his beloved rug in a case of mistaken identity, an affable stoner gets embroiled in a kidnapping caper when all he wants is a new rug.
(30 words)

This movie raises a question in my mind:? if the script for the Big L had been written by an outsider with no credentials, no representation, no track record, would it have gotten a reading no matter how well-crafted the logline?? And if the script got read, would anyone have been willing to put up the money, assemble the talent to produce it?
