Spoilers ahead for Avengers: Endgame.
As a result of the time travel plot mechanic in Avengers: Endgame, many characters of past entries in the Marvel Cinematic Universe create an appearance in the highly-awaited film. That includes the likes of Tilda Swinton as the Ancient One from Doctor Unusual , Robert Redford as Alexander Pierce out of Captain America: The Winter Soldier, and John Slattery as Iron Man’s dad Howard Stark from Iron Man 2, Ant-Man, along with Captain America: Civil War. There are just two major returning characters from the standalone Thor movies Too, in Natalie Portman as Jane Foster, and Rene Russo as Thor’s mother Frigga.
However, while Russo spent time on the collections of Avengers: Endgame, given the extended scene she shared with future version of her son, Portman didn’t. In a meeting with Entertainment Weekly, Endgame directors Anthony and Joe Russo revealed the scenes involving her personality Jane Foster are only leftover shots from 2013’s Thor: The Dark World, the previous time Portman reprised the role. That said, the famed actress did donate to Endgame in some way: her voice.

“A small bit of voice-over when she’s speaking in the distance, that is it,” Anthony told EW. If you remember from Endgame, we first see her speaking to some Asgardians from an area, with her conversation partially drowned in the conversation between Thor (Chris Hemsworth) and Rocket (voiced by Bradley Cooper). There’s another shot of her afterwards from up close, when Rocket sneaks up behind her to find the Aether — that constitutes among the six Infinity Stones — which has attached itself to Foster, as moves the plot in Thor: The Dark World. But she quickly wakes up and walks off-screen.
