Sons of Anarchy is back on our screens for their final season. If you watched the first episode, then you heard The Forest Rangers cover of Bohemian Rhapsody. I liked it so much I thought I'd share it with you. Don't worry, the video is not a spoiler for the show:

Entertainers have always been good at recycling. If something worked well in the past, there is a good chance we will see it again in the future. I'm sure Queen wouldn't mind, after all they themselves found success with their cover of this Elvis Presley song.

Recycling isn't limited to musicians. Michael Bay is so good at it that he turned a 1980's television show into four Transformers movies. Now he's at it again with the Ninja Turtles. Game of Thrones is an HBO 'original series', but before that it was a series of books.

When film makers can't find an idea from a book or an old t.v show, there is always comic books. Guardians of the Galaxy is the latest comic book to hit the big screen, but it certainly won't be the last. We expect this list of comic turned to films to continue to grow for a long time.

Recycling is considered a less risky venture than creating new. It's easier to adapt an existing story than write a new one. Specially if you use a comic, which is in near perfect film script format already. If a story was popular in the past, then there's a good chance that a new audience will also like it.

Then there's the existing fans, how many people saw the Harry Potter films because they had read and loved the books? Existing fans can be hard to please. We've all been to a movie and heard someone say 'the book was better'. I said it myself after watching 'The Wolf of Wall Street'. I enjoyed the film, but even three hours wasn't enough time to tell the full story.

A friend of mine is a comic book expert. He spent 20 minutes telling me why Man of Steel, was flawed. Apparently Superman has a strict code of behavior, which was contradicted in the film. Despite the flaws, he still bought it on Blu Ray. Existing fans may prefer the original, but they will support the new format.

Recycling is a format that works, and we will continue to see it. The only question is, what will resurface next?
