Besides the examples given in this thread, there is also another famous Bollywood actor who stuttered but somehow overcame it and now he is one of the finest actors in India. You won't find out if you can act or not without first trying. Props for entering the acting program, however. Just give it your best and see where it takes you. Just know that you WILL stutter, people WILL laugh at you, you WILL feel bad, but take those in your stride and always move forward. Don't give up. Maybe you will find a way to overcome your stutter when you are acting.
