Jennifer loves TV, especially science fiction. She also loves late-night talk shows, due to her insomnia. Alien: Earth is definitely one of her favorite shows, and she jumps on any chance she gets to write about it. Even on her days off, she will claim an Alien Earth article if one is available.

Jimmy Kimmel and Jimmy Fallon are two of her favorite late-night hosts, and Conan O'Brien before he left his show.

Her Alien: Earth coverage for ScreenRant is by far the work that she is most proud of so far.

She was initially a finance and political editor, but her passion for pop culture convinced her to transition into entertainment journalism.

During her off time, she loves to binge-watch cooking shows such as Kitchen Nightmares. Jennifer also loves spending time with her daughter and cherishes every moment of it.

The X-Men have gone international for Avengers: Doomsday.

Marvel Studios is putting the X-Men in the spotlight as Avengers: Doomsday moves closer to its theatrical release. The brand-new international poster was first spotted in Japan and posted on X. The poster puts the mutant team front and center in the upcoming film's growing amount of promotional material and merchandise.

The newly surfaced artwork showcases the X-Men's iconic logo. Rather than featuring individual characters, the poster focuses on the identities of the different groups or characters who will play major roles in Avengers: Doomsday. Similar designs have been spotted for the titular team, The Fantastic Four, and Black Panther.

The X-Men’s presence in the movie is obviously not a secret. Marvel Studios has already promoted the team countless times. Several actors from the earlier X-Men films before the mutants entered the Marvel Cinematic Universe have also been confirmed to join Avengers: Doomsday's massive ensemble cast. The returning X-Men stars include James Marsden (Cyclops), Patrick Stewart (Professor X), Ian McKellen (Magneto), Rebecca Romijn (Mystique), Alan Cumming (Nightcrawler), and Kelsey Grammer (Beast).

Exactly how large a role the mutants will have in Avengers: Doomsday remains unknown, but Marvel has made it clear that the multiverse will be an integral part of the movie. The synopsis says that heroes from three separate universes will unite to face off against Doctor Doom. That setup provides a solid explanation for why characters from throughout Marvel's different eras will appear together on the big screen.

The Fantastic Four will also be part of the crossover, with Pedro Pascal (Reed Richards / Mister Fantastic), Vanessa Kirby (Sue Storm / Invisible Woman), Joseph Quinn (Johnny Storm / Human Torch), and Ebon Moss-Bachrach (Ben Grimm / The Thing) reprising their roles alongside other MCU veterans. Additional returning actors include Chris Hemsworth (Thor), Anthony Mackie (Captain America), Paul Rudd (Scott Lang / Ant-Man), Letitia Wright (Shuri), and Florence Pugh (Yelena Belova).

Robert Downey Jr., who previously played Iron Man, will also return to the MCU in a completely different role. The Marvel icon will be taking on a villainous mantle this time, Victor von Doom. Marvel has not revealed enough information about the storyline to establish exactly how his plan connects the three timelines.

Avengers: Doomsday will be released in theaters on December 18, 2026.
