This is a round-up of the Star Wars: Episode VII cast.
Han Solo (Harrison Ford):
The original Star-Lord. Smuggler, outlaw and owner of the Millennium Falcon. Not much is known about if Han has changed since Episode VI but it will be interesting to find out.
Poe Dameron (Oscar Isaac):
The new character that I'm most excited to see is X-Wing pilot Poe Dameron, who works for Princess Leia and the Resistance. He is rumoured to be searching for Luke Skywalker's lightsaber, which brings him into contact with other members of this list.
General Hux (Domhnall Gleeson):
Not much is known about General Hux, except for the fact that he is a leader of the new villainous group the First Order.
Rey (Daisy Ridley):
Rumoured to be Han Solo's daughter, Rey is a scavenger living on Jakku who is probably the owner of BB8 (see above). She will meet Finn and that will probably make her join the Resistance.
Finn (John Boyega):
A former Stormtrooper, Finn discovers Skywalker's lightsaber, making him a target of the First Order. He is also rumoured to be Lando Calrissian's son.
Maz Kanata (Lupita Nyong'o)
Maz is a pirate, who owns a castle that is visited by smugglers, hitch-hikers and other riff-raff (maybe Han Solo?). No actual shots have been shown, except concept art.
Luke Skywalker (Mark Hamill):
The last remaining Jedi, whose lightsaber is found by Finn and Rey, therefore probably making them meet at some point.
Leia Organa (Carrie Fisher):
Not much is known about Leia at the moment, however we do know that she is still with the Resistance.
Kylo Ren (Adam Driver):
Probably the main villain for Episode VII, Kylo is a Darth Vader fanatic (he even modelled his mask after Vader's). He is a member of the First Order and also the Knights of Ren.
Supreme Leader Snoke (Andy Serkis):
Nothing has been confirmed except that he will be a member of the First Order.
