Recommend some movies about mice.

I recommend you a classic comedy "Catching Rats"

After his father died, the two brothers inherited a thread factory and an old house. My brother didn't want to sell the thread factory, and his snobbish wife kicked him out of the house. My brother's restaurant was suddenly in trouble and forced to sleep on the street. The two brothers then moved to the old house left by their father. By chance, they learned that this dilapidated old house was originally the work of a master architect and was priceless. There's only one problem. There is a very clever mouse in the old house. To this end, the two brothers fought a protracted war with this little rodent. It sounds easy, but in fact, their opponents are not simple, and the two brothers are exhausted. Finally, when the two brothers were desperate, the mouse led them to open a thriving cheese factory.
