The film hints at a possible role for various villains in this or later films in the franchise.
One clip shows cases in which Doctor Octopus's tentacles and the Vulture's wings can be seen.
An OsCorp computer screen is also seen, which, when zoomed in, shows file entries for Venom, Dr Connors (the Lizard) and Dr Morbius.
While Shailene Woodley's Mary Jane Watson role was cut from the film, a shot apparently shows the back of the actress's head.
The Rhino (Paul Giamatti), Electro (Jamie Foxx) and Norman and Harry Osborn (Chris Cooper and Dane DeHaan) - either of whom might take on the role of the Green Goblin - are confirmed to feature in The Amazing Spider-Man 2.
The Lizard featured in Sony Pictures' first reboot film in 2012.
The third film - which will arrive in 2016 - is expected to featured the villainous team called the Sinister Six.
The Amazing Spider-Man 2 will be released in the UK on April 18, 2014 and May 2, 2014 in the US. Watch the trailer below:
