In Australia, the title was changed to "Suddenly 30" because distributors thought audiences would misunderstand the original title.

The editor in chief pins a picture of J-Lo on the wall and it changes position from being perfectly straight to very crooked between shots.

The blindfold Jenna is wearing when she is 13 is made out of the same material/pattern as the eye cover she is wearing when she wakes up when she is 30.

When Matt gives back the Dream House to Jenna in his old bedroom in 2004, there is no visible wishing dust on the roof, just a little of it stuck to the side wall. However there is plenty of it on the roof later when Jenna sits down in the backyard and the wind starts to whirl it up.

The Poise article that Jenna is reading at 13 ("Thirty, Flirty & Thriving"), features the apartment that she later lives in at 30.

It was shipped to theatres under the name "Sugar and Spice".

When Jenna and Lucy are standing outside the club where they have just had drinks, Lucy pulls out a cigarette as Jenna is talking to Matt. She is holding it in her right hand and as she says she is going back inside she puts the cigarette in her left hand with her lighter. She turns to walk back in and the cigarette is back in her right hand.

When Jenna discovers that Sparkle magazine stole her redesign concept, she walks out of her office and a bus passes by with a billboard advertising the new issue of Sparkle, featuring her design, "on newsstands now".
