Former "Xena" star Lucy Lawless – last seen in a cameo in "Spider-Man" – has signed to appear in "The Ugly Americans", which is due to start production in Prague next month. The story revolves around two American high school pals on the verge of graduation. One is passing German courtesy of his German pen pal, who translates his homework. But when the German expresses feelings for the teen and suggests a meeting, the student rebuffs the mysterious writer, thinking it’s the act of a sexual predator. He soon discovers the pen pal is actually a fetching fraulein, and the pair sets off on a trans-European road trip. Michelle Trachtenberg, Travis Wester, Jacob Pitts and Scott Mechlowicz co-star.
