Alec Baldwin is showing fans the childish side of himself in the new film 'Boss Baby.' The trailer was just released on Thursday and it is truly adorable. However, don't tell that to the Boss Baby himself, as the film tells a story about an 'in charge' baby who arrives to a new family and takes over immediately, taking every step necessary to get the love and attention he deserves. 'Boss Baby' premieres in theaters on March 31st 2017.
