Leto plays the scientist Michael Morbius (Michael Morbius), who tries to cure his rare blood disease by using bat DNA, but becomes a vampire.
In the first trailer, Mobius walked past a Spider-Man poster covered with graffiti, although it is not clear which Marvel world the movie is set in.
The film was originally scheduled to be released in July 2020, and then originally scheduled to be released in March and October.
It is not clear whether the Covid-19 pandemic is the cause of this latest delay.
“Mobias” is directed by Daniel Espinosa.
