Parents need to know that Night at the Museum: Secret of the Tomb follows the same formula as the first two movies (Night at the Museum and Night at the Museum: Battle of the Smithsonian), this time taking Larry and his gang of historical friends on the road to London. Expect more of the same slapstick (and sometimes crude) humor fans will already be familiar with. Some kids might find a few scenes scary -- ancient statues come to life, a giant snake attacks the group, characters are trapped by a volcano's fiery output, and at one point it appears as if significant characters have died -- and there's talk that the "end will come." There's also some flirting and kissing between a Neanderthal and a security guard, as well as mild language ("hell," etc.) and a little drinking. While this installment isn't as lively as the first two, it does have positive messages about friendship and loyalty.
