 While a clip was not actually seen (though dialog is heard), there  is a scene in Pedro Almodovar (qv)s  _What have I done to deserve this? (1984)_ (qv) in which the  grandmother and her eldest grandson attend a showing of  _Splendor in the Grass (1961)_ (qv). As they leave the theater, the  poster (Spanish) is clearly seen in the background.
