how much time did he spend in jail?
how much?
shareAccording to Wikipedia:
Clifford Irving spent 17 months in prison at the Danbury Federal Correction Facility in Danbury, CT, and at Allenwood Prison in Pennsylvania. He returned $765,000 in advance money (including the $750K that his wife used to open an account in Switzerland).
Clifford's friend and co-author of the fake autobiography, Richard Suskind, served 5 months in jail of a 6 month sentence.
I forget whether Edith Irving actually served any prison time, although it might have been mentioned in the movie at the end.
Yes it's mentioned at the end.
She served one year in a swiss prison.
