'The Notebook,' a 2004 film based on the novel by Nicholas Sparks, helped build the careers of Ryan Gosling and Rachel McAdams into superstardom and also sparked off-screen romance between the two actors. But the film could have had a different leading lady.

Jessica Biel, who still regrets losing the film to Rachel McAdams, recently admitted to Elle magazine that she really wanted the role of Allie in The Notebook.

It's quite hard to believe that Biel could have been turned down by anyone, but it's true that the bombshell has now revealed that she regrets about the one film role that got away.

Biel said that she had been considered for the role of Allen in the 2004 love story and had been forced to perform next to Gosling for director Nick Cassavetes in strange circumstances.

That's one that I wanted so badly, she told Elle magazine. I was in the middle of shooting 'Texas Chainsaw Massacre,' and I auditioned with Ryan Gosling in my trailer -- covered in blood.

Nick Cassavetes put me through the wringer in an interesting, excitingly creative way, she added. However, in the end, the role went to Rachel McAdams, but Biel didn't take it too hard.

Biel also explained how actors lost out on most wanted roles of all the time, saying there's a million that get away.

In the interview, Biel weighed in dating fellow actors. I think those are the people you meet and so it just kind of happens. Let me tell you: It never happens on purpose.

But what do you think? Who was suitable for Allen role, Biel or Rachel?
