Science fiction movies are expected to have a high budget with all the special effects and demanding production setups. However, history has proven that even high-budget films do not guarantee a blockbuster performance. One such example was Disney's biggest box office bomb, the animated movie Mars Needs Moms, which had a budget of $150 million yet only raked in $39.5 million in sales. Meanwhile, one good example of a box office hit with a low budget is the original installment of the horror film Paranormal Activity. This 2007 movie had a budget of $15,000 but earned more than $193 million.
