Roger Ebert wrote a great review of The Incredibles with an interesting comment at the end:

The Incredibles also has a character inspired by Q, Bond's gadget-master. This is Edna Mode, known as E and voiced by Brad Bird, who also wrote and directed. She's a horn-rimmed little genius who delivers a hilarious lecture on the reasons why Mr. Incredible does not want a cape on his new uniform; capes can be as treacherous as Isadora Duncan’s scarf, and if you don't know what happened to Isadora Duncan, google the poor woman and shed a tear.

So I googled Isadora and found this website which explains that she was a famous dancer who always wore an incredibly long scarf, which proved unbelievably fatal:

As she took her seat in the car neither she nor the driver noticed that one of the loose ends fell outside over the side of the car and was caught in the rear wheel of the machine.

The automobile was going at full speed when the scarf of strong silk suddenly began winding around the wheel and with terrific force dragged Miss Duncan, around whom it was securely wrapped, bodily over the side of the car, precipitating her with violence against the cobblestone street. She was dragged for several yards before the chauffeur halted, attracted by her cries in the street.

Medical aid immediately was summoned, but it was stated that she had been strangled and killed instantly.

Isn't that crazy? What a way to go. But anyway, go see The Incredibles! It's definitely one of the best movies of the year!
