Between his latest film and The 40-Year-Old Virgin, the big four-oh is obviously an important number for Judd Apatow (and, presumably, many others). But the semi-autobiographical This Is 40 doesn't just see the famously self-obsessed writer/director looking back at his own life, it also sees him returning to one of his earlier films.

Billed as the "sort-of sequel" to Knocked Up, which is really just a fancy way of saying spin-off, This Is 40 follows Debbie (Leslie Mann), Pete (Paul Rudd) and their two kids (Maude and Iris Apatow) as the couple navigates turning 40, and all the mid-life crises that come with it.

But can This Is 40 top its "sort-of" predecessor, which went on to critical acclaim and big money at the box office thanks to Apatow's patented combo of R-rated humor and heartfelt sentiment? Or does it land closer to overly narcissistic Funny People territory? To find out, I crunched the numbers.
