what kinds of problems could arise from cultural differences when marrying someone from different culture?


I haven´t been married, but based in the movie, i think a situation like of this kind is particular i every situation. when you married someone you're suposed to love him/her, and should be able to solve the "problems" with maturity, pacience, talking with your mate, as we saw in the movie. probably the real problems would come when a important desition has to be taken like the name of a kid, the religion he/she will believe in, the baptisim, and topics related to that. 
refering to manners and habits related to the culture, both of them must have respect and consideration about the other, may be in the process of living together both yield in some discussions or treats of behavior. in conclusion, for me,  a marriage between person of two different cultures could be succsesfull if both of the members are capable of respect, underestand, acept, and dialogue.


another thing to note it's the priorities,  human rigths, must not be less important than other things, there are cultures where physicall deformation or integrity its violated.  moral and ethics issues would be decisive  at time of marriage.
