We have seen a few epic marriage proposals here at SF Globe, but this one just might be my favorite. Not only did Liam put a lot of time and thought into a proposal that would wow the love of his life, he included her family and their friends. Renting out a movie theater is a pretty epic way to propose - and can cost a pretty penny, depending on its location. It can range from hundreds of dollars in a relatively small town to tens of thousands in a big city.
