In Night at the Museum: Secret Of The Tomb, Ben Stiller once again plays Larry the security guard who is effectively custodian of the lives of his exhibits. As the movie begins, his night at the museum in New York goes horribly wrong. In the middle of a meticulously-choreographed routine, the exhibits refuse to do as instructed. All mayhem breaks loose as the characters wreak havoc and generally upset the celebs who are in attendance.

It transpires that the museum’s magic tablet - found during an exhibition in Egypt decades ago – is corroding. This means that the very thing that causes the exhibit characters to come to life is threatened. 

In search of a solution, Larry travels to the British Museum, and the NY exhibits also smuggle their way across to lend a hand. In old Blighty, the motley crew come up against the guile and ambition of Lancelot (Dan Stevens) who suddenly ditches his quest for the Holy Grail as he develops a sneaking regard for the magic tablet. 

So it goes, but your reviewer found Night at the Museum: Secret Of The Tomb tired and lame, like something running out of steam at the tail end of its natural life. (This one is said to be the last one, thankfully.)  Dialogue is very limp, and aside from being the very busy Larry, Stiller also plays a decidedly unfunny Neanderthal.

Robin Williams plays his final role, once again as President Roosevelt. Cameos from Dick Van Dyke and Mickey Rooney are supposed to lend comedic gravitas, but their contributions just fizz uselessly, like damp squibs. Hardly matters to the producers, as the first two films made $988 million (€789 million) between them.
