"Bridget Jones's Diary" was yet another variation on the Cinderella story, but instead of becoming the belle of the ball, Renee Zellwegger's Bridget stayed pretty much the same pumpkin throughout, but got her prince anyway.

In director Judd Apatow's male version of the story, "Knocked Up," the pudgy, dorky, unemployed Ben (Seth Rogen) beds and weds the scrumptiously blonde, career-focused Alison (Katharine Heigl) without ever upgrading his wardrobe, tightening his abs, or getting a proper job.

Kensaku Kakimoto's "Baum Kuchen" might be described as "Knocked Up" tripled — and some. Calculating the romantic math of this fantastic voyage through four worlds is like unrolling the title confectionery — that is, damn near impossible. One thing is clear, however: The three mismatched brothers these worlds revolve around make Bridget and Ben look like hot items in the romantic marketplace.
