You can try this one...

#####
library(RCurl)
library(rjson)

ids <- c("tt0110074", "tt0096184", "tt0081568", "tt0448134", "tt0079367")
titles <- data.frame()

for ( i in 1:length(ids)) {
req <- paste("http://www.imdbapi.com/?i=", ids[i] , "&tomatoes=TRUE",
sep="")
u <- getURL(req)
j <- fromJSON(u)
titles <- rbind(titles, as.data.frame(j))
}
#####

I am sure it can be done more efficient...
