The best movies make us fall in love with their stories and characters along with the stars that play them. This talent is what causes collectors clamor for autographed movie star memorabilia.

Movie autographs for sale today can be found on a wide range of souvenirs from old film stills to iconic props. They also range wildly in collectability. Autographed memorabilia by short-lived popular actors such as James Dean can achieve incredibly high prices, as can signatures by actors who rarely signed their name. Souvenirs from living actors with ample opportunity to sign typically achieve lesser prices.

Though the demand for popular stars' signatures has contributed to an increased presence of forged or fraudulent signatures, authentic autographs are still plentiful on the auction market. If you have a favorite star or movie in mind, chances are you can still commemorate that adoration with an autograph.
