Stellan Skarsgard will appear in The Avengers
Actor Stellan Skarsgård recently revealed that he will star in The Avengers, portraying the same character he plays in Thor.

While IMDB lists Stellan Skarsgård's character as "Professor Andrews," a recent interview indicates the character is named Doctor Selva, a scientist in New Mexico. There is no Professor Andrews or Doctor Selva in The Avengers comic books, so this character remains a mystery, for now.

Due to the ambiguity of the character's name, there is speculation that Stellan Skarsgård may play a secret villain in The Avengers.

Joss Whedon is directing The Avengers from a script by Zak Penn. Production is scheduled to start in April.
