Visible crew/equipment: When Picard, Data and Worf are on the planet, just a few shots after they leave the shuttle, Picard drives a sharp left curve. If you look at him in this shot, it is not Patrick Stewart sitting on the driver's seat, but his stuntman, who is not even wearing goggles. (00:12:45)
Revealing mistake: Near the end of the film, when Picard bends the pole down to stab Shinzon, the pole supposedly goes through him and out the other side, but the prop travels several inches down his waist. A shot later, you can see the prop pushing against Shinzon's clothing, obviously not piercing anything. (01:39:17)
Captain Picard: In his quest to be more like us, he helped show us what it means to be human.
Trivia: At the end of the movie, B-4 starts singing, causing Picard to smile because he knows Data's memories are surfacing. This is almost identical to a scene in Voyager when the Doctor was copied onto the matrix of Dr. Zimmerman to restore his program. It ended with Kes having the identical reaction that Picard had to B-4.
Question: If Shinzon is Picard's clone, wouldn't it have been easier to have Patrick Stewart play both parts? Tom Hardy doesn't even look like Stewart.
Answer: Shinzon was always intended to be much younger than Picard - the whole point is that he's a Romulan project that was ultimately abandoned - he hasn't gone through the accelerated aging process. Patrick Stewart could not have convincingly played a version of his character who was that young. And Tom Hardy does bear a distinct resemblance to a young Patrick Stewart if you look properly.
