20 Famous actors you never noticed were guest stars on TV shows
Every big-name Hollywood actor has to make their start somewhere. After all, people aren't usually born famous. Instead they typically climb the ladder by taking on smaller bit-parts or guest star roles in smaller productions, until they finally land the part that turns them into a household name.
This means that, if you go back and re-watch some of your favourite TV shows, you might notice that a huge celebrity once made an appearance in it before they were famous. If you're used to seeing them as the dashing lead on the big screen, then it can be pretty damn jarring to see them again on some cable network on a low-budget soap. But don't worry if you're too lazy to go back and watch all those hours of TV: we're already done it for you. Scroll down to check out some of the most surprising famous actors to guest star on TV.
