Of course he'll escape, there wouldn't be a show if he was stuck in there forever.
If you mean things that are likely to have recurring themes within the series then: 1. Cracks 2. Myth 3. Pandorica
The Pandorica was built by an alliance of the Doctor's greatest foes who were under the mistaken belief that the Doctor was responsible for the cracks in the universe. It was built to imprision the Doctor, presumably indefinately.
No it's not real.
Originally, nothing was. The Pandorica was empty, because it was built to hold the Doctor, after he'd been lured there. He was not in it long though, he'd engineered his own escape, getting Rory to open it from the outside. A mortally wounded Amy was then placed inside, since death is a form of escape, the Pandorica could even prevent that. She then spent the next 2000 years in stasis, until her young future self touched it, giving the Pandorica the DNA information it needed to heal the adult Amy inside.
well since rory had the sonic screwdriver to open the pandorica then the doctor was out put his screwdriver in amys pocket to the future doctor knew what to do
The Pandorica Opens/The Big Bang
River song left it.
I think he's supposed to have stolen his TARDIS to escape, but theres a bit of a plot hole in that the eleventh doctor somehow got a new TARDIS when he wasn't allowed to return to galifrey
Eleventh Doctor was created in 2010.
A Christmas Special.
Not who, but what. The Pandorica was an elaborate prison created by the Alliance (a coalition of The Doctor's greatest enemies) to hold The Doctor for all eternity. Their reasoning for this was not to be rid of The Doctor for their own gain, but to stop the cracking of the universe, which they believed was The Doctor's doing. In fact it was caused by the TARDIS exploding mysteriously on the 26th of June 2010 (the date of the finale's broadcast).
July 10th at 8:00 PM CST I believe.
