Osmosis Jones

Similarities: 

• Both the Immune System and the movie, Osmosis Jones, have cells with specific jobs. The white blood cells, in this case, Osmosis Jones, kill any dangerous substance.
• Like the Immune System, whenever a disease appears, white blood cells such as Osmosis Jones as sent to neutralize the disease.
• Diseases, in both real life and the movie, cause harm to the body which causes the immune system to respond.

 Differences:

• The most obvious example would be that the cells in the movie are anthropomorphic, that is they contain human characteristics and unique personalities.
• Another difference is Drix's ability to fight the disease, Thrax, when real-life cold pills only subdue the symptoms of a cold.
• There is also the abundance of technology in the body, such as cars and various machines that help the cells in their various jobs.
