Hey!
Everything has its pros and cons and so does the acting profession;
So  below i am mentioning the a disdavantages i feel can be faced by an actor:
actors must learn to leave their ego behind during auditions, and to take rejection with a grain of salt. Acting is a business, and your body and mind is the product being sold. Actors need to market and brand themselves, in order to make connections and stand out from the competition. Since there are so many actors and so little acting parts, often most people are just not right for the part.


There are many false people in the acting industry who will stab actors in the back by talking about them behind their back, and taking jabs at flaws, especially the physical appearances of actors.


It's difficult to date or be married while being a dedicated actor. Actors will often have two-three weeks where they're working to the bone every day, and then will have 2-3 weeks with no jobs. In film, usually callbacks will be the day after an audition, a wardrobe fitting will be the following day, and the scene will be shot on the fourth day. Often casting calls are given at most 24 hours before an audition, so actors are often required to cancel plans, even funerals and family events at the last minute in order to make it to the audition.

Hope it helps!
