Do you have a source for that title (other than IMDB/Wikipedia)?

In addition to seeing that any site in Italian refers to this film with the title "jumper - senza confini", in addition to seeing that the blue-ray and DVDs for sale (AMAZON for example) report on the covers this title and in addition to seeing the word "senza confini" combined with the word "jumper" on all the posters of the film in Italian (practically any reference, including original posters) no, I have no further feedback. If you try to find in google.it "jumpers - senza confini", it is very likely that you too have a doubt about the right title. If you think I'm wrong, sorry for the waste of time, I just wanted to be useful.

Ciao!

Italian title updated. Thanks.
