Im talking about that actor/actress that was in a big hit movie but they themselves never made it big in the movies, however they still pop up in a movie or tv show sometimes, I was watching the movie cant hardly wait the other night and recognized one of the teachers in the film as Jamie Donnelly who played jan in the movie grease, the girl who sang that brusha brusha brusha song, and another one I allso noticed playing A teacher on the TV show 7TH heaven was the actress Janette Goldstein who was in the movie titanic, she was the irish woman with the kids that sadly drownded, and ive seen janette in alot of other rolls, she was in star trek generations, but janette never made it as A star. and these are just a couple there are so many more that just pop up sometimes, infact sometimes if I see a familiar name in the credits of a movie or tv show sometimes ill watch that show just to see what they look like if I have not seen them in a recent film.
