Extra (stylized as "extr@") is a language education television program franchise that was scripted in the format of a Friends-esque sitcom. It was in production from 2002 to 2004, and is mainly marketed to the instructional television market for middle school and high school language classes. Four versions were made, each in a different language; English, French, German, and Spanish. The English version was co-produced by Channel 4 Learning and RAI CPTO (Production Centre of Turin) for RAI Educational. All of the episodes were written by Louise Clover. The English version has 30 episodes, and the other three languages have 13 episodes each. The plot of the 13 episodes is nearly the same in all the language variants. Hector/Sam, with only a very basic grasp of the featured language, comes to stay with his pen pal, Bridget/Sacha/Sascha/Lola. Living with Bridget/Sacha/Sascha/Lola is roommate Anna/Annie/Ana. Sleazy and sly neighbor Nick/Nico/Nic/Pablo lives across the hallway. Hector's/Sam's efforts to get to grips with the language provide the dynamic for the series' language learning content. The series is particularly suitable for adolescents and young adults who can relate to the contextual setting and implied meanings in the screenplay. The series ended with Sam and Annie's wedding being canceled, ending with a cliff-hanger; however, the English version had 17 more episodes which provides a better understanding of the character, continuing with Nico and Sacha beginning to date and facing problems, and Sam and Annie wanting to break up. In the end, Sam was offered a job opportunity in the U.S as a producer. The 30th episode, Love hurts, ended with Sam questioning "Should I go?", and there were no more episodes produced, hinting at Sam's departure. Thus the plot begins and ends with Sam. The episode descriptions are based on the English version. The plots are almost the same in the language versions. Word play, as with any internationalization, is usually untranslatable and involves slight differences.
