The Avengers have been around since 1963, and the "A" with the arrow has been their symbol as far back as anyone can remember. Of course, the 2012 live-action feature film "The Avengers" reintroduced audiences to the iconic logo. This latest version has been given an "Ultron" makeover, but it's still very recognizable indeed.

Even if you've never seen "A Clockwork Orange," chance are you are familiar with this logo. The 1971 crime drama directed by Stanley Kubrick is a classic and disturbing look at youth culture. The film made Malcolm McDowell a movie star. If you've never seen it, treat yourself to this Kubrick masterpiece.

Here's a logo audiences quickly fell in love with. Before "Back to the Future" was even released in 1985, the logo had caught our attention and helped sell us on the Michael J. Fox flick. Naturally, once the movie hit theaters, we could not wait for the sequel. The franchise spawned two sequels and always incorporated the classic logo design.

Blade Runner was released in 1982 and its memorable logo was a highlight of John Henry Alvin's classic poster design. If you're an 80's baby, you probably know Alvin's work from E.T., Gremlins and several Disney films like: The Little Mermaid, Beauty and the Beast and Aladdin. Over the years, the film has developed a massive cult following. This is another "must-see" movie.

Frozen's logo is the most recent addition to this collection. The 2013 Disney 3D computer-animated musical was inspired by Hans Christian Andersen's fairy tale The Snow Queen. The movie was a massive commercial success and made $1.3 billion worldwide. All the classic Disney ingridients were present, great charcters, music and a unique media campaign. It's likely this logo is more recognizable at the moment than many of the classics listed here.

The Harry Potter film series based on J. K. Rowling's insanely popular books consists of eight films. Needless to say, the logo became part of the fabic of childhood's around the globe for the better part of ten years. The films received critical acclaim and went on to make $7.7 billion worldwide. It's doubtful you will find many people unfamiliar with this logo.
