For 1986, best picture was Platoon, Best Actress was Marlee Matlin (for Children Of A Lesser God), Best Actor was Paul Newman (for The Color Of Money). Album of the year was Graceland by Paul Simon.
If a year is divisible by 4 it is a leap year - except:
If it is a centenary year (ie ending in 00), it must be divisible by 400.
As 1986 was not a centenary year, it need only be divisible by 4....
