The organisers of Alamo City Comic Con have given a heads up to attendees about a very special photo opportunity coming their way. Tomorrow at 12pm CT sharp, tickets go on sale for the first ever joint photo session with none other than David Tennant and John Barrowman. It's a chance in a lifetime opportunity for anyone who ever imagined taking part in a scene with those two TARDIS heroes, the Tenth Doctor and Captain Jack.

The event takes place at the Henry B Gonzalez Convention Center, San Antonio, Texas on Saturday 29th October.

Tickets will be available from this link tomorrow - but be there when they launch, they're extremely limited!

Other attendees at the event which runs from 28-30th October are Billie Piper and the casts of Gotham and Marvel's Daredevil. Find out more about the convention here.
