"Entourage" had so many guest stars and cameos throughout its run, it's hard to remember all the celebs that came in contact with Vincent Chase and company. Here are a few you may (or may not) remember...
"Heroes" star Ali Larter actually appeared in the pilot episode of the HBO series as herself. She angrily looks for Vince -- curses a flyin'! -- and it's implied that the two of them had some sort of a thing going on...
At the height of "High School Musical" fame, Zac Efron appeared on the 6th season of the show as himself.
You may recall that singer/actress Mandy Moore (as herself) dated Vince and they went on to star in the fictional "Aquaman" blockbuster together. She was the "Aquagirl" to his "Aquaman."
"Transparent" star Jeffrey Tambor played a hilarious fictionalized version of his actor self in a handful of episodes.
Yup, Mrs. Ari Gold dated the celebrity chef on the show during the time when she and the big shot agent were separated. They even dined at his fictional Los Angeles restaurant called Flay's.
When Marty calls, you answer. And the legendary director offered Vince a chance to star in his adaptation of "The Great Gatsby" in Season 5. This was all before Baz Luhrmann announced he was actually taking the classic book to the big screen.
In Season 1, Ari tried to sneakily sign comedian Sarah Silverman after bumping into her outside of Jimmy Kimmel's green room. (The pushy agent was been banned from going inside.)
David Schwimmer had a hysterical turn as himself (and Ari's "favorite friend') rejecting pitches to play Ross-like neurotic characters.
