Rossellini, 56, said the reason she plays the male role in many of the 1-minute "Porno" short films for the second season of the SundanceChannel.com Web series is the active nature of the gender in the wild, the New York Post reported Sunday.
"Well, I was already playing a starfish, or a bug. I thought that stretch was much bigger, to be a sea creature than to play a male! But the real reason is sometimes (males) move more," Rossellini said.
The second season of "Porno" premieres online Wednesday.
The "Death Becomes Her" actress, who is the daughter of the late actress Ingrid Bergman, donned insect costumes for Season 1 of "Porno" to act out wildlife sex activities.
Rossellini told the Post while she is open to revisiting her role on "30 Rock" as the ex-wife of actor Alec Baldwin's character, she has not heard of such a reunion.
"Not that I know of. But I would love to!" Rossellini said. "I never really watch much television, but I do follow some of '30 Rock.'"
