Television is catching up to the movies fast. From the writers to the actors to the directors, TV has stepped it up in recent years and there are more quality shows now than ever before. So it's no big surprise we're seeing TV shows do things usually reserved for movies. One interesting development is the use of one actor in multiple TV roles. The movies sometimes use CGI to pull this off, something previously too expensive to consider for TV. But those days are over. Networks are spending money and using new tricks to portray twins and lookalikes on the small screen. These are some of the best.
