Depending on who you ask, the average lifespan of a vampire can vary from hundreds to thousands to infinity years. Well, when it comes to the Underworld franchise, the same applies to Kate Beckinsale, the face of the series’ protagonist Selena.

Sure, 13 years between the first and fifth films do show a minimal difference in what Beckinsale looks like—it’s only natural—but otherwise, she’s the only immortal face of Selena in the live-action films.

There are talks of a 6th movie coming out. Back in 2017, the creator of the franchise Len Wiseman said Beckinsale will be coming back as Selena for this one too, but a year later, Beckinsale herself said she won’t as she has done so many already, so it is yet to be determined.
