A Viking Rock band (yup, it's a genre) takes its name from the goddess.

In The Matrix Revolutions, The Merovingian runs a nightclub called Club Hel. Doesn't sound like a place where we'll be partying anytime soon.

How would you like to live in Hel? The residents of Hel, Poland do it every day!

"Names have been changed…" : In her earlier, Proto-Germanic (read: really, really Old German) form, Hel may have been known as Halja. (Source.)
