does anyone know the name of this film?

it is quite an old film think late 80 early 90 maybe older

these fats could be wrong as i saw the film 4 or more years ago

it is about this young boy who goes to a musem (or i think it was) and he opens this tomb and then a mummy comes out

he then takes the mummy home with him and keeps him for a day

he dresses the mummy up as a human and takes him around town

the mummy has to get back to the museum before midnight so that he can find his true love

or somehting like that

For some reason i think it is called something like midnight mummy

but i could be completely wrong

oh and it was funny but i dont know if the genre was comedy :S ... if that makes sense

please help :D
