Reggie's math teacher discusses the number of vertices, edges, and faces you get when you cut a sphere. However, spheres in our universe have no vertices, edges, or faces. He's apparently describing Euler's invariant for polyhedra, perhaps the actor couldn't pronounce "polyhedra" so they replaced it with a geometric object ("sphere") he could pronounce.

The license plate on the family vehicle is the same as on the taxi in Oneida that picks up Eleanor and Reggie at the bus station.

At the end of movie when Eleanor is playing the coronet she is taking a breath while the coronet is playing, revealing that she is not actually playing the coronet.

At the end of the movie when Eleanor's part -time job babysitting Reggie cones to and end,they both lament over "breaking up"after the bond they established;,however,it defies credulity not to believe that Reggie could -and would-make Eleanor's position full-time with simply a request to his mother.

In an early set up ,Barbara(Debra Messing)tells her maid Esa (Olgo Merediz)to "make sure all the girls who interview for the nanny position take off their shoes before entering the library."That position ,of course,is what Eleanor(Leighton Meester)ends up taking.But when she's actually in the library conducting the interview ,both Eleanor and Barbara are clearly seen wearing shoes.It seems the Lady of the Manor forgot about her own rule.

During the piece that Reggie has composed for the quartet near the beginning of the movie, you can see Violins and Violas as well as the Piano and Cello. Eleanor also remarks on how beautiful the Violas and Violins sound together, but when they perform the piece, you can only hear the Cello and Piano.
