Mrs. Doubtfire

Daniel Hillard (Robin Williams) is no ordinary father, so when he learns his ex-wife (Sally Field) needs a housekeeper, he applies for the job. With the perfect wig, a little makeup and a dress for all occasions, he becomes Mrs. Doubtfire, a devoted British nanny who is hired on the spot. Free to be the "woman" he never knew he could be, the disguised Daniel creates a whole new life with his entire family. (official distributor synopsis)
