High School Musical, and High School Musical 2: Sing It All Or Nothing! He is the fraternal twin brother, and acting partner of Ashley Tisdale's character Sharpay Evans. He is played in the High School Musical movies by Lucas Grabeel.
Ryan Evans along with his sister Sharpay, have starred in 17 school musicals. Ryan is the nicer of the two, though he is not that bright, he could read stuff on the computer, and the call back sheets, but could not read a sign that the Basketball team made out of letters on their shirts which read "Go Drama Club!". Ryan is a member of the East High Drama Club, and seems to have a collection of hats as in every scene he is in he has a different hat on (numbering up to nine hats throughout the movie). He was willing to go along with his sisters schemes to get Troy and Gabriella to miss the call backs, and even said he was proud to call Sharpay his sister when he heard them. Ryan is almost always seen with his sister Sharpay.
