Marvel's action movies and the superheroes in them seem to get bigger with each instalment. Thor gets more muscly, Groot branches out and the Hulk, well, hulks.
Enter Ant-Man, Marvel's latest in its vast colony of spin-offs. With less hype than the Avengers and a rocky development, this superhero stayed true to his name and crawled in under the radar.
The excellent Paul Rudd plays the down-on-his-luck ex-con Scott Lang. After getting out of prison, Lang is recruited by Dr Hank Pym (Michael Douglas) and daughter Hope van Dyne (Evangeline Lilly).
Armed with a suit which can shrink its wearer down to miniscule size, Lang joins an army of ants to battle a foe who wants to weaponise the technology.
Like most Marvel hero movies, the plot is pretty predictable. However, Ant-Man stands out with a fast pace and plenty of jokes.
Epic scenes with slapstick antics keep the audience on their toes and laughing: a particularly effective fight scene involves a toy train set and a mishap with a Thomas the Tank Engine.
The main cast is strong, but the side characters are equally enjoyable too: Michael Peña's fast-talking Luis is a scene-stealer.
While it may be competing against major action contenders this summer, even from within its own studio, Ant-Man ups the ante by keeping things fresh, exciting and fun.
