Anyone know this movie or TV show?

I don´t really have much...all I remember is one scene where two guys (go back in time maybe?) visit the castle of Vlad the Impaler in order to retrieve some important artifact?

I remember it as a good scene, the castle was surrounded by the impaled bodies of Vlad´s enemies and the guy that played Vlad was excellent.

I thought maybe it was a film called Timeline (from the Michael Crichton book) but on IMDB I can see no reference to Vlad...
