4 Reasons Mamma Mia! Is the Ultimate Summer Movie

There's no wonder why the actors appear to be so joyful — they got a free vacation to Greece! Part of what makes the film so endlessly watchable is the magnificent scenery. Nobody can argue that Mamma Mia! didn't take full advantage of the beautiful beaches on the once relatively-unknown Skopelos island. Fans of the film might want to consider visiting, as there's a Mamma Mia!-themed tour there now. Filming on location also gave the film a reality that would be hard to create using CGI like so many films do today.
