Let's face it, rock and roll is for the young. Axl Rose needs to find a second occupation, and acting would be better than rock music. He has always been a great performer on stage, so he should take that part of his talent and emphasize it instead of becoming an aging embarrassment to himself.
Yes, Axl Rose would benefit from branching out into acting, like other rock stars, because being involved in a variety of things is a good way to improve credibility and name recognition. Athletes and actors who participate in Dancing With the Stars often do this so that other people will hear of them. It is a good way to become more famous.
Axl Rose would benefit immensely from branching out into acting as opposed to solely remaining a musician. He is and has been one of the most famous people in America and around the world for years. He already possesses many of the required traits for a successful actor from his years performing as the front man for Guns N' Roses and performing in their various music videos. Being an actor requires a strong recognizable personality, confidence, and the ability to connect with an audience, which are all talents he had to cultivate in order to be a successful lead in a band. Not to mention the ability to memorize a large number of lines and while reciting them back and making them feel fresh every time in his live shows.
Axl Rose is too much of an icon in American music history to be able to branch out into acting. Viewers would not be able to see past his image and accept him in other roles. He is imprinted far too deeply in all of our minds as a music artist to be able to break free of that.
I doubt there is any real way for Axl Rose to benefit from branching out into acting, as other rock stars and music personalities have done. I believe he would be far better off to focus solely on Guns N' Roses, his original entrance into the music industry. I believe in order from to transition, he would more than likely have to sell out and no one really wants to see that.
