Any idea how to optimize such code? (Now nullity check is done twice..)

private var trendingMovies: List<TrendingMovie>? = null

fun doSth(){}
	if(trendingMovies == null)
		getTrendingMovies()
	else
		trendingMovies?.let { showTrendingMovies(it) }
}

private fun showTrendingMovies(list: List<TrendingMovie>){}

Local variable comes to my mind, but I wonder is it the best we can do?

fun doSth(){}
	val trendingMovies = trendingMovies

	if(trendingMovies == null)
		getTrendingMovies()
	else
		showTrendingMovies(trendingMovies)
}
