Originally, Brad Silberling wanted Sunny to be pure CGI. While he eventually used real babies for the part, at least four of Sunny's scenes have a CG baby because they would be impossible or dangerous for a real child to do. Among these are shots of Sunny hanging on to a table by her teeth, and catching a spindle with her mouth, and the scene where she is entangled with the Incredibly Deadly Viper.

Klaus in the books is nearly blind without his glasses while, in the movie they are only needed for reading.

Violet in the book was unable to put braids in her hair because they would stay together, but in the movie she has braids nearly the entire time.

Prune trees in the front yard, and not to mention, 172. Prepare a delicious dinner for myself and my troupe
When Klaus finds a spy-glass in his father's desk, there is a box of green cigarettes lying beside it, labelled VFD.

The real ending of "The Wide Window" is as follows: after rescuing the orphans from the leeches (and drowning Aunt Josephine), Count Olaf, still disguised as Captain Sham, would return to the dock, where Mr. Poe and the person of indeterminable gender are waiting.

Mr. Poe would then stand up to Olaf, but the villain quickly runs away with his henchman, leaving Poe and the Baudelaires locked up behind them.
The strange, menacing-looking engine in the railroad crossing scene very strongly resembles Pennsylvania T-1 4-4-4-4, an experimental engine built in 1942 by the Baldwin Locomotive Works, and used exclusively by the Pennsylvania Railroad. All of the real T-1's were sold for scrap by the early 1950s.
Because the train scene was filmed on a forced-perspective set, Industrial Light & Magic did something called "lattice deformations "to squeeze the computer-generated train (including the smoke) onto the forced-perspective tracks.

When looking at Aunt Josephine's photo album, the Baudelaires stumble across a picture of the society their parents and family members were a part of. In the top right-hand side of the picture, a person's face is partially blurred out, though the appearance seems to be that of Jim Carrey, hinting that Count Olaf might have been formerly part of the society, or disguised himself to get close to them.
According to the illustrations in the original books, Violet wears a dress with the V-cuffed lower sleeves (a very common attire in space operas), Klaus wears a sweater with a button-down shirt underneath, and Sunny wears a small dress. The orphans' costumes in the movie are noticeably different.
