"[It’s] kind of similar to the Bonnie Bedelia character in the first one just as far as it focuses a bit on their relationship and then she kind of gets thrown into the plot as it goes," said Winstead.
Since Lucy was only a toddler in the original film, Winstead kind of had free reign to create her character. "She’s briefly shown in the first "Die Hard" but you really don’t know anything about her as a person."
Compared to low budget horror movies and indie dramas, "Die Hard 4" is a whole new style of acting for Winstead. "On a big action film, it’s a lot more kind of sleeping in your trailer for hours and hours while they set things up, and then you go and you act for 20 minutes and then you go back to your trailer. It’s hard to stay excited and inspired so you have to work a little harder to give a good performance in that kind of situation. But it’s still a lot of fun."
