She loved how they included a throwback from the first 'Top Gun' movie in its sequel that was released more than 30 years after the 1986 original, reports aceshowbiz.com.
She told USA Today, "I'm still hoping that 'Legally Blonde 3' is gonna come together in the right way."
She added, "It's just like 'Top Gun'. They waited a long time to make another version of that movie, and I loved the nostalgia piece they incorporated in it."
"So definitely that gave us a lot of inspiration about what we would want to do with Elle Woods and make sure that we had all those same touchstones that mattered to people (back) then."
Witherspoon says the characters are so beloved to her that she wants to make sure the move is perfect.
She added: "I feel like these characters are my friends, so I safeguard them. I would never make the subpar, mediocre version of their story."
