Mary Bennet has a crush on Mr Collins - Pride and Prejudice (1995) 

"Mrs. Bennet wished to understand by it that he thought of paying his addresses to one of her younger girls, and Mary might have been prevailed on to accept him. She rated his abilities much higher than any of the others; there was a solidity in his reflections which often struck her, and though by no means so clever as herself, she thought that if encouraged to read and improve himself by such an example as her's, he might become a very agreeable companion." - Pride and Prejudice, chapter 22

While my sister and I were rewatching the 1995 Pride and Prejudice for the gazillionth time, we discovered a secret of Mary Bennets: she has been harboring a crush on Mr. Collins! If Mr Collins wasn't so obnoxious and conceited he might've noticed, but then again, Mary might’ve never been attracted to him in the first place.
