This episode was made available for free before the official air date on Amazon's Unbox service as a promotional tactic. A change in strategy after NBC Universal didn't renew their contract with iTunes to sell episodes.
At least three versions of the pilot episode were produced. The first version had Mae Whitman cast as Jaime's deaf sister, a character that sparked criticism from hearing-impaired rights groups when it was learned the actress wasn't deaf in real life. This version of the pilot was one of several widely circulated on the Internet during the summer of 2007; at the 2007 San Diego Comic Con, an edited-down, half-hour version of this pilot was shown to audience members as a preview of the new series. For broadcast, however, several scenes were filmed, and the cast changed with a new actress playing Jaime's sister, and the hearing-impaired subplot being eliminated.
This is the only episode in which Lucy Hale is credited as Lucy Hale. In every other episode she's credited as Lucy Kate Hale.
