April Webster, C.S.A., was one of Lost's casting directors, under the auspices of Grass Skirt Productions, LLC.
On the casting of Lost, Webster has stated that it presented her with a unique challenge:
I got an e-mail from (co-creator) Damon (Lindelof) that said, 'Well, here's the good news: We know what these six characters are going be. Now here's the bad news: There are more characters, but we don't know what they do, their gender or how old they are.' 
- Was nominated for an Emmy in 2006 for "Outstanding Casting For A Drama Series", along with co-workers Veronica Collins Roone, C.S.A., and Mandy Sherman, C.S.A.
- Has worked as a casting agent as far back as the 1980s in the television show Knight Rider, and therefore appears to be the senior member of the group including Roone and Sherman
- Appeared in the 20/20 "Lost Special" (S26 E1396) of May 6, 2005
