Well, to make a long story short, Jason Segel is not Jewish! (though he considers himself Jewish)
Since Jason Segel's mother is not Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him not Jewish (though once again, he DOES consider himself to be Jewish). Though he is not Jewish, His father is Jewish , and by Reform Judaism and Reconstructionist Judaism, who accept both matrilineal (by mother) and patrilineal (by father) descent views, he is considered Jewish.
Jason Segel (whose full birth name is Jason Jordan Segel) was born on January 18, 1980 in Los Angeles, California, U.S..
He is known for his role as Marshall Eriksen in the CBS hit sitcom How I Met Your Mother, as well as his work with producer Judd Apatow on the cult classic, short-lived television series Freaks and Geeks and Undeclared; the films Forgetting Sarah Marshall; Knocked Up; I Love You, Man; Gulliver's Travels; Bad Teacher; Despicable Me; The Muppets and The Five-Year Engagement.
