Marvel has released the first trailer for Avengers: Endgame and it looks like viewers are in for an emotional rollercoaster.
The clip opens as Tony Stark (Robert Downey Jr) is floating through space, recording a final goodbye message for Pepper Potts (Gwyneth Paltrow).
"Hey Ms Potts if you find this recording, don't feel bad. Part of the journey is the end", he says.
"Just for the record being adrift in space with zero promise of rescue is more fun than it sounds.
"When I drift off I will dream about you", Stark tells her.

Meanwhile, Scarlett Johansson's Black Widow confirms that Thanos (Josh Brolin) has wiped out half of all living creatures on Earth, which was the shock ending of the last Avengers film, Infinity War.
A voiceover says: "We lost, all of us. We lost friends, we lost family, we lost a part of ourselves.
"This is the fight of our lives."
The trailer also picks up after the cliffhanger at the end of Ant Man & The Wasp, showing Paul Rudd's Scott Lang making contact with Chris Evans' Captain America and Johansson's Black Widow.
Avengers: Endgame will be released in April 2019.
