The new application in partnership with VYou will see the actor answer five questions over the next ten weeks, and is designed to enable fans to interact directly with the page in three different ways.
The principal function is the ability to record a personal video response to the question, which can then be shared with other fans who watch the video stream, appearing after Matt's original answer.
The initial question on the site is:
If you could travel anywhere in time where would you go?
In future, fans themselves will be able to submit questions, and further interaction is providing in the form of a voting system in order to determine the favourite question - the ones with the most votes will then be answered by Matt himself.
