Mr. Deeds/Big daddy

"Mr. Deeds: Small-town guy Longfellow Deeds goes to New York City to collect a $40 billion inheritance from a long lost uncle, even living in a palatial mansion with the services of an unusual valet. Things get better when he mets a beautiful woman. But money changes everything, and things aren't what they seem - his sweetie is actually a journalist feeding reports of his outrageous behavior to the press! Now, its up to Deeds to straighten everybody out."@en
"Big daddy: Sonny is 32-years-old. He's a law school graduate. He's got a nice apartment in Manhattan. There's just one problem. He does nothing, except sit on his butt and live off an investment that was the result of a meager lawsuit he won a year ago. After his fed up girlfriend leaves him, he comes up with the ingenious idea to adopt a five year old boy to showcase his newfound maturity. But things don't go as planned, and Sonny finds himself the unlikely foster father that will change his perspective on just looking out for himself."@en
