American actor who played the elderly Admiral Mark Jameson, growing younger scene by scene under heavy make-up, in the first-season Next Generation episode Too Short a Season.
Clayton Rohner is an American actor who guest starred in the first-season Next Generation episode Too Short a Season. He plays Admiral Mark Jameson, an aged and wheelchair-bound negotiator sent to Mordan IV to deal with a hostage crisis.
Jameson has secretly taken an alien rejuvenation drug, and Rohner, then in his early thirties, began the episode under extensive old-age make-up that was reduced in stages as the character grew younger. The story reveals that Jameson armed both sides of a civil war decades before.
Rohner is also known for the 1980s films Just One of the Guys and April Fool's Day and for many later television guest parts.
