Lost premiered on September 22, 2004, and instantly became a pop culture sensation. Touted as having the most expensive TV pilot ever (at the time), it was far from a sure bet, but thanks to a blockbuster-sized two-part pilot episode that successfully introduced an ensemble cast of 17 (!) regulars, alongside several cryptic mysteries, Lost became an overnight hit.
On the 20th anniversary of Lost, Inverse looks back on one of the best TV debuts of all time, with one longtime Lostie and one newbie to the show.
