R can have a bit of a learning curve... There are several ways to achieve
your goal - depending on what you want:
test_df <- data.frame(Movie = letters, some.value = rnorm(26))
test_df$Movie[1:10]
test_df$Movie[sample(c(1:26), 10)]
test_df[sample(c(1:26), 10), ]
Do read a tutorial or two on R - "Introduction to R" as suggested by David
or something else - so you can explain the code above to yourself.

Hey,
I am a beginner in R.
How do I read last 10 values from column- Movie, from a dataset?
Some questions are so simple that they strongly suggest no prior effort at
self-leanrning. In such cases the usual recommendation given at Rhelp is
that you read an introductory text. Many of us used the "Introduction to R"
that is shipped with every copy of R:

Pls help.
