Let's face it Marissa spent a ton of time in front of her driveway in season one of The O.C..It was almost as if she lived on the curb! The most memorable of the driveway scenes was when Ryan left the Cohen's house for the first time at the end of the pilot episode and also when Marissa watched Ryan drive off with Theresa in the last episode of the first season "The Ties That Bind". Comparing the two above images (first episode goodbye to last episode goodbye) you can see Mischa Barton's character's overall facial looks changed a whole lot within the first season - she looks much older on the right - less baby fat too. Which makes a lot of sense because she was one of the only REAL teenager that played a teenager in The O.C..Find out how old she was plus the age of the rest of the gang here!
