Was the movie "Insominia" with Al Pacino, writen by Frobenius and
Skjoldbjaerg orginally a novel?  If so, please supply details
(ie.when, based on true event?,is it in print,etc.)If not, what was
the history, if any, behind the creation of thes movie?

The 2002 film "Insomnia" is a remake of a 1997 Norwegian film (also
titled "Insomnia") whose original script was not based upon a novel
nor a true event, but was written directly for the screen by Nikolaj
Frobenius and Erik Skjoldbjærg. Hillary Seitz adapted the
Frobenius/Skjoldbjærg screenplay for the 2002 version.

The Stephen King novel "Insomnia" is totally unrelated to either of
these movies.
