That was in Superman II, lol. No that wouldn't work - essential they already use the slingshot theory to do space travel by using the gravity of the planet to increase speed. Going around the sun would certainly make you go faster for sure but also melt your ship to particles at the same time.
nah wasnt from superman 2. in superman 1 he flew around the earth and reversed it. sling shot around the sun from star trek 4 voyage home lol
