This National Geographic documentary on Friday - 'World's Biggest Beasts' on Channel 5 was pretty good.
There was one error though
Spinosaurus was certainly longer than rex but not as massive.
The 22 ton estimate seems to be from from an older paper - a more recent figure of 7 tons seems to be far more realistic (compared to 8.4 to 10 tons for rex).
Just look at the size comparison of the skeletons.

*Edit.
I found that the old study that gives the 22 ton estimate has been widely discredited - 7 tons it is.
Apart from that it was entertaining with a lot of very recent research - the quad launch of giant Pterosaurs for example.

There are also two documentaries on tonight which will no doubt delight Creationists.
Channel 4 on
Homo naledi - 'First Humans: The Cave Discovery' at 8.00PM and 'The Two Million Year Old Boy' on More 4 at 9.00.
