Macaulay Culkin will only do another movie with his brother Kieran Culkin if it is "just right" for them both.
The duo last appeared on the big screen together in 1992's Home Alone 2: Lost in New York, and they have since gone on to act in projects independently, but Macaulay, 45, would not be "allergic" to film reunion with 43 year old Kieran.
