Superhero movie round-up: 'Batman v Superman,' Aquaman, 'Spider-Man'

Actress Jena Malone played Rocket in 'Sucker Punch.'

"Batman v. Superman" is linked with "The Hunger Games" actress Jena Malone, director Zack Snyder provides more detail on an Aquaman cameo, and a "Spider-Man" cast list rumor circulates.

- Barbara Gordon in Batman v. Superman? -

Jena Malone played Johanna Mason in the "Hunger Games" films and worked with Zack Snyder, director of "Batman v. Superman: Dawn of Justice," on 2011 action movie "Sucker Punch."

Associated with "Batman v. Superman" since October 2014, she was at first thought to be playing Batman's sidekick, Robin.

Having dyed her hair red, speculation matched her up with the coloring of "The Dark Knight Returns" female Robin, Carrie Kelley.

But another character from the Batman universe is also a fellow coppertop -- Commissioner Gordon's daughter, Barbara -- and it's she who Malone is playing now.

That's according to the Latino Review, citing three separate sources on the matter. The revelation opens the door to two possible Barbara Gordon alter egos: another sidekick in Batgirl, or Batman's intelligence adviser Oracle.

Barbara was introduced as Oracle in the "Suicide Squad" comics, and Snyder is executive producing on that series' film adaptation which is booked for August 2016.

- Aquaman surfacing in March -

Speaking of Snyder, the director told Empire Magazine that there's to be a cameo appearance from another DC superhero, Aquaman, in March 2016's "Batman v. Superman."

Jason Momoa would pop up in a cameo role, Snyder confirmed in conversation with Empire Magazine, introducing Aquaman several years in advance of a first "Justice League" ensemble in 2017 and his own solo feature in 2018.

- Spider-Man cast list -

Meanwhile, in Marvel's world, a rumored cast list has been doing the rounds (Latino Review), mixing names already known with a bunch of exciting though unconfirmable suggestions.

Tom Holland as Peter Parker and Spider-Man and Marisa Tomei as his Aunt May were already known. A Robert Downey Jr. appearance makes sense, given that Holland screen-tested with him, and his Iron Man character is a linchpin of the Marvel Cinematic Universe.

Others, if correct, suggest an interesting direction for the webspinning reboot. Among them, there was Billy Zane as The Vulture, Jason Biggs as Scorpion, Timothée Chalamet ("Homeland") as a young Harry Osborn and future Green Goblin, Jacob Latimore of "The Maze Runner" as Flash Thompson and newcomer Rachel G. Fox as Mary Jane Watson were all intriguing selections.
