Big Momma's House/Big Momma's House 2/Dr. Dolittle/Dr. Dolittle 2

A collection of four comedy films. In 'Big Momma's House' (2000), FBI Agent Malcolm Turner (Martin Lawrence) is sent undercover to protect a vital witness and her son.

When a notorious bank robber escapes from prison, Turner heads for the house of key witness Big Momma, where he believes the robber is heading.

But Big Momma has gone away and so Turner decides to impersonate the old lady in order to trick the robber.

However, when he meets and falls for the con's ex-girlfriend, things get far more complicated than he ever imagined.

In 'Big Momma's House 2' (2006), in order to trap a brutal bank robber, Malcolm goes deep undercover, impersonating a fun-loving granny known as Big Momma.

But saving the country is the least of Big Momma's problems as he takes on his ultimate challenge - being nanny/housekeeper to the suspect's dysfunctional family.

In Dr. Dolittle (1998), an updating of the 1967 musical, a young boy finds he can talk to animals, but his disapproving father forces him to repress his gift.

Now a doctor with a family, John Dolittle (Eddie Murphy) rediscovers his ability after accidentally running over a dog.

He begins to communicate with animals again, and soon has a queue of ailing pets in his waiting room.

However, John's colleagues, worried for his sanity, have him committed to an asylum.

The sequel, 'Dr. Dolittle 2' (2001), sees the doctor having to save an endangered species, the Pacific Western Bear, and its natural habitat, a forest that is under threat from the lumber industry.

The trouble is he only has three weeks to find a mate for the lone female of the species (voiced by Lisa Kudrow) left in the wild and the only candidate he can come up with is a performing bear (voiced by Steve Zahn) with a penchant for junk food.

Not only has Dolittle got a massive task on his hands, he also has to contend with the forest's animal version of the Mafia.
