Hate to break it to you, but not everyone can be a famous actor / actress, sorry to burst your bubble. But, there are literally casting calls for extras in movies and TV all the time and everywhere. Not too long ago we came across a casting call for extras in Season Four of Vikings. How cool would that be? Epic battles, maybe some screaming in the background, running to and fro, chaos and destruction. The casting itself was in Ireland, but you can do a quick google search for extras casting and the list is endless. There are services where producers and would be producers post their calls and there are also a lot of city / town municipal film divisions that post casting calls to their local websites.
While the fun is of course finding something great like Vikings or some other epic TV show / mini series or whatever, the act of simply being “on set” is really cool, you do of course want to make sure that you get on a show or in a film that is actually going to get made – because it’s infinitely more fun when you and all your friends maybe try and hit the pause button to try and find you somewhere in the background… “Wait, I think that’s… no…”
If you do manage to find yourself somewhere in Europe for the casting, then you can always retire to your chateau and pat yourself on the back for job well done and have a cognac in the library. Life is good.
